Backup / restore via monoctl

[jastBytes]

Currently the backup is only to be configured via helm chart as cronjob. Restoring works via helm chart too, but is not very convenient. As a proposal it would be nice if an administrator could trigger a backup job from monoctl as well as restore a specific backup via monoctl.

AC:

• Trigger a backup via monoctl backup create as system admin
  • either to be stored on the already configured s3 storage
  • or to be downloaded by monoctl directly if the backup is finished
• Trigger a restore via monoctl backup restore as system admin
  • either from backups listed via monoctl backup list which shows which backups exist in s3
  • or by uploading an backup
• Add documentation for this
