Some upcoming features require more than one export location and possibility to mark them with specific labels like fast/slow or rw/ro. So, implement 'export locations metadata' feature: - It allows to set any key-value pairs for each export location. - These key-value pairs can be set only by share manager using response from various share driver methods. - Example of update is implemented using Generic driver "create_instance" method. - Metadata can be updated for any export location in any place of share manager where db function "share_export_locations_update" is called. - Keys from export location metadata table will be added to 'share' and 'share instances' views as export location attributes. Also: - Add new attr 'is_admin_only' for existing export locations model. If set to True, then only admins will be able to see them. Unless policy is changed. - Add APIs for reading export locations by share and share instance IDs. - Remove 'export_location' and 'export_locations' attrs from 'share' and 'share instance' views. - Bump microversion as new APIs implemented.
