F #5989: Live update of Virtual Network attributes
co-authored-by: Pavel Czerný <pczerny@opennebula.systems>

* VNET updates trigger a driver action on running VMs with NICs in the
  network.

* VNET includes a sets with VM status: updated, outdated, error and
  updating. With VMs in each state.

* VNET flags error situations with a new state UPDATE_FAILURE.

* The same procedure is applied when an AR is updated (only VMs in that
  AR are updated).

* A new options in the one.vn.recover API call enable to recover or
  retry this VM update operations.

* The following attributes can be live-updated per VNET driver:
    - PHYDEV (novlan, vlan, ovs driver)
    - MTU (vlan, ovs driver)
    - VLAN_ID (vlan, ovs driver)
    - QINQ_TYPE (ovs driver)
    - CVLANS (ovs driver)
    - VLAN_TAGGED_ID (ovs driver)
    - OUTER_VLAN_ID (ovs driver)
    - INBOUND_AVG_BW (SG, ovs driver + KVM)
    - INBOUND_PEAK_BW (SG, ovs driver + KVM)
    - INBOUND_PEAK_KB (SG, ovs driver + KVM)
    - OUTBOUND_AVG_BW (SG, ovs driver + KVM)
    - OUTBOUND_PEAK_BW (SG, ovs driver + KVM)
    - OUTBOUND_PEAK_KB (SG, ovs driver + KVM)

* New API call one.vm.updatenic, allows to update individual NICs
  without the need of detach/attach (only QoS supported).

* Update operations for: 802.1Q, bridge, fw, ovswitch, ovswitch_vxlan
  and vxlan network drivers.

* VNET attributes (old values) stored in VNET_UPDATE to allow
  implementation of update operations. The attribute is removed after a
  successful update.

* Updates to CLI onevnet (--retry option) / onevm (nicupdate command)

* XSD files updated to reflect the new data model

* Ruby and JAVA bindings updated: new VNET state and recover option, new
  VM API call.

* Suntone and Fireedge implementation (lease status, recover option, new
  states)

TODO: Virtual Functions does not support this functionality

F #5516: New backup interface for OpenNebula
co-authored-by: Frederick Borges <fborges@opennebula.io>

BACKUP INTERFACE
=================

* Backups are exposed through a a special Datastore (BACKUP_DS) and
  Image (BACKUP) types. These new types can only be used for backup'ing
  up VMs. This approach allows to:

  - Implement tier based backup policies (backups made on different
    locations).

  - Leverage access control and quota systems

  - Support differnt storage and backup technologies

* Backup interface for the VMs:

  - VM configures backups with BACKUP_CONFIG. This attribute can be set
    in the VM template or updated with updateconf API call. It can include:

    + BACKUP_VOLATILE: To backup or not volatile disks

    + FS_FREEZE: How the FS is freeze for running VMs (qemu-agent,
      suspend or none). When possible backups are crash consistent.

    + KEEP_LAST: keep only a given number of backups.

  - Backups are initiated by the one.vm.backup API call that requires
    the target Datastore to perform the backup (one-shot). This is
    exposed by the onevm backup command.

  - Backups can be periodic through scheduled actions.

  - Backup configuration is updated with one.vm.updateconf API call.

* Restore interface:

  - Restores are initiated by the one.image.restore API call. This is
    exposed by oneimage restore command.

  - Restore include configurable options for the VM template

    + NO_IP: to not preserve IP addresses (but keep the NICs and network
      mapping)

    + NO_NIC: to not preserve network mappings

  - Other template attributes:

    + Clean PCI devices, including network configuration in case of TYPE=NIC
    attributes. By default it removes SHORT_ADDRESS and leave the "auto"
    selection attributes.

    + Clean NUMA_NODE, removes node id and cpu sets. It keeps the NUMA node

  - It is possible to restore single files stored in the repository by
    using the backup specific URL.

* Sunstone (Ruby version) has been updated to expose this feautres.

BACKUP DRIVERS & IMPLEMENTATION
===============================

* Backup operation is implemented by a combination of 3 driver operations:

  - VMM. New (internal oned <-> one_vmm_exec.rb) to orchestrate
    backups for RUNNING VMs.

  - TM. This commit introduces 2 new operations (and their
    corresponding _live variants):

    + pre_backup(_live): Prepares the disks to be back'ed up in the
      repository. It is specific to the driver: (i) ceph uses the export
      operation; (ii) qcow2/raw uses snapshot-create-as and fs_freeze as
      needed.
    + post_backup(_live): Performs cleanning operations, i.e. KVM
      snapshots or tmp dirs.

  - DATASTORE. Each backup technology is represented by its
    corresponfing driver, that needs to implement:

    + backup: it takes the VM disks in file (qcow2) format and stores it
      the backup repository.

    + restore: it takes a backup image and restores the associated disks
      and VM template.

    + monitor: to gather available space in the repository

    + rm: to remove existing backups

    + stat: to return the "restored" size of a disk stored in a backup

    + downloader pseudo-URL handler: in the form
      <backup_proto>://<driver_snapshot_id>/<disk filename>

BACKUP MANAGEMENT
=================

Backup actions may potentially take some time, leaving some vmm_exec threads in
use for a long time, stucking other vmm operations. Backups are planned
by the scheduler through the sched action interface.

Two attributes has been added to sched.conf:
  * MAX_BACKUPS max active backup operations in the cloud. No more
    backups will be started beyond this limit.

  * MAX_BACKUPS_HOST max number of backups per host

* Fix onevm CLI to properly show and manage schedule actions. --schedule
  supports now, as well as relative times +<seconds_from_stime>

  onvm backup --schedule now -d 100 63

* Backup is added as VM_ADMIN_ACTIONS in oned.conf. Regular users needs
  to use the batch interface or request specific permissions

Internal restructure of Scheduler:

- All sched_actions interface is now in SchedActionsXML class and files.
  This class uses references to VM XML, and MUST be used in the same
  lifetime scope.

- XMLRPC API calls for sched actions has been moved to ScheduledActionXML.cc as
  static functions.

- VirtualMachineActionPool includes counters for active backups (total
  and per host).

SUPPORTED PLATFORMS
====================
* hypervisor: KVM
* TM: qcow2/shared/ssh, ceph
* backup: restic, rsync

Notes on Ceph

* Ceph backups are performed in the following steps:
    1. A snapshot of each disk is taken (group snapshots cannot be used as
       it seems we cannot export the disks afterwards)
    2. Disks are export to a file
    3. File is converted to qcow2 format
    4. Disk files are upload to the backup repo

TODO:
  * Confirm crash consistent snapshots cannot be used in Ceph

TODO:
  * Check if using VM dir instead of full path is better to accomodate
    DS migrations i.e.:
    - Current path: /var/lib/one/datastores/100/53/backup/disk.0
    - Proposal: 53/backup/disk.0

RESTIC DRIVER
=============
Developed together with this feature is part of the EE edtion.

* It supports the SFTP protocol, the following attributes are
  supported:

  - RESTIC_SFTP_SERVER
  - RESTIC_SFTP_USER: only if different from oneadmin
  - RESTIC_PASSWORD
  - RESTIC_IONICE: Run restic under a given ionice priority (class 2)
  - RESTIC_NICE: Run restic under a given nice
  - RESTIC_BWLIMIT: Limit restic upload/download BW
  - RESTIC_COMPRESSION: Restic 0.14 implements compression (three modes:
    off, auto, max). This requires repositories version 2. By default,
    auto is used (average compression without to much CPU usage)
  - RESTIC_CONNECTIONS: Sets the number of concurrent connections to a
    backend (5 by default). For high-latency backends this number can be
    increased.

* downloader URL: restic://<datastore_id>/<snapshot_id>/<file_name>
  snapshot_id is the restic snapshot hash. To recover single disk images
  from a backup. This URLs support:

  - RESTIC_CONNECTIONS
  - RESTIC_BWLIMIT
  - RESTIC_IONICE
  - RESTIC_NICE

  These options needs to be defined in the associated datastore.

RSYNC DRIVER
=============
A rsync driver is included as part of the CE distribution. It uses the
rsync tool to store backups in a remote server through SSH:

* The following attributes are supported to configure the backup
  datastore:

  - RSYNC_HOST
  - RSYNC_USER
  - RSYNC_ARGS: Arguments to perform the rsync operatin (-aS by default)

* downloader URL: rsync://<ds_id>/<vmid>/<hash>/<file> can be used to recover
  single files from an existing backup. (RSYNC_HOST and RSYN_USER needs
  to be set in ds_id

EMULATOR_CPUS
=============

This commit includes a non related backup feature:

* Add EMULATOR_CPUS (KVM). This host (or cluster attribute) defines the
  CPU IDs where the emulator threads will be pinned. If this value is
  not defined the allocated CPU wll be used when using a PIN policy.
