This feature let's cloud admin to proxy VM connections to any service through the hypervisor. VMs uses a link local IP that is forwarded to a local proxy. This simplifies VM network requirements, e.g. to access gateway, vaults, configuration services etc...
Implementation:
- Use network namespaces to isolate VNET networking. ip netns command is executed through a wrapper to limit sudo access to commands.
- Add tproxy.rb app to manage a group of daemons on HV nodes.
- Use unix sockets for communication between proxy peers. "Inner" proxy runs in the netns without any network access. "Outer" proxy handles HV connections to services.
- Use OpenNebulaNetwork.conf + 'onehost sync -f' for configuration. Proxy can be defined per network.
* Cleanup oned in case of initialization error
* Fix monitoring after onemonitord restart. The code includes a "hook" point in case a driver is re-started so custom code can be executed. InformationManager sends the list of hosts and raft status in this case.
* B #5801: Update error msg, in case of duplicated drivers
This commit implements a transparent proxy for OneGate service (as well as any other TCP service)
* #6281: Disable legacy OneGateProxy
* Implement OneGateProxy in VN drivers
- Fix LXC linuxcontainers monitor action (error setting header)
- Update context packages URL reference to point to the new location
- Add lxc marketplace utility to sudoers file (removed in a previous
commit)
- Remove CentOS from supported OS list in LXC marketplace
(CentOS9_Stream includes some failures that need further debugging)
in TM cloning script
- Added function get_ds_attribute to tm_common.sh to get a given attribute from a Datastore
- Using falloc preallocation mode on the qemu-img commands since it is faster than using full preallocation
- Note the cloning script when using the TM_MAD = ssh does not use qemu-img command. Instead it uses the tar command, hence it ignores the QCOW2_OPTIONS parameter
- Deleted get_ds_attribute function since it is no longer needed
- SPARSE is inherited from Datastore on oned.conf
- Changed resize statement so it uses same syntax as the clone statement

This commit implements the in-place restore of VM backups. Selected VM disks will
be replaced with the specified backup:
* A new API call has been added to the XML-RPC API (`one.vm.restore`) with
the following arguments:
- VM ID to be restored, needs to be in **poweroff** state
- IMAGE ID of the backup to restore
- INCREMENT ID, only for incremental backups, the increment to use
(defults to -1 to use the last increment available)
- DISK ID of the disk to restore (defaults to -1 to restore all VM
disks)
* Datastore drivers needs to implemente a new operation `ls`. This new
operation takes the VM, image information of the backup and datastore
information and returns the restore URL for the disks in the backup.
* This commit includes the implementation for qcow2 and ssh drivers,
ceph will be implemented in a separated PR. The new driver action is
`restore host:vm_dir vm_id img_id inc_id disk_id`
* The restore operation is performed in a new state `PROLOG_RESTORE`
rendered as `RESTORE` and `rest` in short form. State in in RSuntone.
TODO:
- Remove any existing VM snapshot (system/disk) in the VM. Note that
snapshots are not included in a backup.
- Ceph drivers
- JAVA, GO Lang API bindings
- Sunstone interface, new state and new operation. Review new state in
RSuntone.

* Update Gemfile
- Add rackup requirement for new sinatra
https://github.com/sinatra/sinatra/blob/main/CHANGELOG.md
Note: when using Sinatra to start the web server,
you now need the rackup gem installed
- newer sqlite3 is not compatible with ruby2.7
* Update almalinux8 to avoid old key
* Refresh Gemfile.locks
