Share Migration Ocata Improvements

Implemented several improvements to share migration
according to spec [1].

Summary of changes:
- Snapshot restriction in API has been changed to return error only
when parameter force-host-assisted-migration is True
- Added preserve_snapshot to API and migration_check_compatibility
driver interface
- Changed all driver-assisted API parameters to be mandatory
- Added validation to prevent 'force_host_assisted_migration' to be
used alongside driver-assisted parameters
- Changed "same host" validation to reject only if the combination
of "host", "new_share_network" and "new_share_type" is the same as
the source
- Updated migration driver interfaces to support snapshots
- Updated zfsonlinux driver, defaulting preserve_snapshots to False
- Updated dummy driver to support preserve_snapshots

Spec update with latest changes since [1] merged
can be found in [2].
