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.
