The snapshot_support extra spec has always meant two things: a driver can take snapshots and create shares from snapshots. As we add alternate snapshot semantics, it is likely that some drivers will want to support snapshots and some of the new semantics while being unable to create new shares from snapshots. This work adds a new extra spec, create_share_from_snapshot_support, that removes the overloading on snapshot_support. It also makes the existing snapshot_support extra spec optional, allowing admins to create types without setting snapshot_support; shares created with such types will not support snapshots.
