[PATCH manager 1/2] ui: dc: backup edit: add filter for guests without backup job

[Elias Huhsovitz <e.huhsovitz@proxmox.com>]

Add a checkbox in the guest selector toolbar that shows only guests
which are not covered by any backup job. The window fetches the guest
list from /cluster/backup-info/not-backed-up once and caches it for the
lifetime of the edit window.

Use a named node filter when the node selector changes instead of
clearing all store filters. This keeps the new filter and the review
filter active across node changes.
