[pve-devel] [PATCH proxmox] notify: remove legacy filters and groups

[Lukas Wagner <l.wagner@proxmox.com>]

The notification system as we know it know underwent a serious overhaul
shortly before its initial release in PVE one year ago. Before the
overhaul, there were filters (the 'inverse' of a matchers as we know
them today) and groups (allowed one to send a notification to
multiple targets at once, they were replaced by being able to select
multiple targets in a matcher).

Unfortunately, this previous iteration of the notification was already
merged and packaged in the pvetest repository, resulting in an unknown
number of systems which may have already been using filters and groups.
To avoid breaking these systems when updating to the overhauled
notification system, we've kept the section config type
for both config sections. In anticipation of a future removal of these
section types, we proactively removed these entries when loading and
saving the notification config file.

It has been a full year now, so I'd argue it is safe to drop these
safety guards now. On the off chance that there are still systems out
there which still have these entries in their notifications.cfg,
a manual removal from the file will be needed after this commit.
