[Share groups] Add scheduler filter ConsistentSnapshotFilter

That will be used for scheduling share groups based on their possibility
to create consistent snapshots.

Also apply following tempest plugin changes:
- Add new 'capability_sg_consistent_snapshot_support' tempest config
option, that will be used for creation of new share group types and used
to prove that scheduling works as expected.
- Fix some share group test attributes from 'only API involved' to
  'API and Backend are involved', because it is so indeed.
