Rodrigo Barbieri 9639e72692 Share migration Newton improvements
At Austin 2016 summit there were several improvements to
Share migration feature discussed. This patch implements
these changes.

Changes are:
- Added 'Writable' API parameter: user chooses whether share must
remain writable during migration.
- Added 'Preserve Metadata' API parameter: user chooses whether
share must preserve all file metadata on migration.
- Added 'Non-disruptive' API parameter: user chooses whether
migration of share must be performed non-disruptively.
- Removed existing 'Notify', thus removing 1-phase migration
possibility.
- Renamed existing 'Force Host Copy' parameter to 'Force
Host-assisted Migration'.
- Renamed all 'migration_info' and 'migration_get_info' entries to
'connection_info' and 'connection_get_info'.
- Updated driver interfaces with the new API parameters, drivers
must respect them.
- Changed share/api => scheduler RPCAPI back to asynchronous.
- Added optional SHA-256 validation to perform additional check if
bytes were corrupted during copying.
- Added mount options configuration to Data Service so CIFS shares
can be mounted.
- Driver may override _get_access_mapping if supports a different
access_type/protocol combination than what is defined by default.
- Added CIFS share protocol support and 'user' access type
support to Data Service.
- Reset Task State API now allows task_state to be unset using
'None' value.
- Added possibility to change share-network when migrating a share.
- Bumped microversion to 2.22.
- Removed support of all previous versions of Share Migration APIs.
