Remove coupling to NotificationBundle

[core23]

Feature Request

This is the last bundle that relies on the SonataNotificationBundle for no good reason. The original idea was to allow async snapshot creation / cleanup. This can also be done via commands and shouldn't take too long for a normal number of pages.

To allow deprecating the usage, we could introduce a new SnapshotManagerInterface with two methods createSnapshotsForSite and cleanupSnashotsForSite.
