Code Issues Proposed changes

Add cast_rules_to_readonly to share instances

Browse Source 
- Add Database migration to introduce the column on the
  share instances model.
- Set the field to True if creating read-only secondary
  replicas, unset while promoting them.
- Set the field to True if drivers don't support writable access
  to migrating shares, or if using host assisted migration.
  Unset if migration fails, or is canceled.
- Expose the field via share-instances and share-replicas
  APIs to administrators.

Supporting read only-access rules is part of the minimum
driver requirements in manila.
