Deprecate CONF.api.allow_instance_snapshots

Browse Source 
The introduction of this option predates Gerrit [1]. It is
not used consistently, since it's not used for createBackup
or shelve APIs which also create snapshots. And it's not
discoverable.

We need to deprecate this option and anyone that cares to
disable snapshots needs to do it via policy.
