- Generic quotas are defined and read from oned.conf (QUOTA_VM_ATTRIBUTE)
- Generic quotas react to the running mode (i.e. account only when the VM is
running). For each quota oned also adds a RUNNIN_* metric
- one.system.config API call has been updated so every user can read
quota configuration:
. Sensitive information is hidden (***)
. Oneadmin group has no longer access to sensitive information
through the API
- CLI has been updated to render generic quotas
- onedb fsck fixes generic quotas reading the configuration from
oned.conf
Other changes in this PR:
- Refactor Quota metrics to use std::vector instead of C array
Squashed commit of the following:
- New methods to Template and Attribute classes to render hidden
attributes as "***"
- Update Quota calls to not include unneeded quotas
