Something changed in requests/urllib3 library and now it sends
requests with url in a lower-case. It affects test_version_discovery
test because we use url in camel-case.

This patch changes test url to lower-case to be compatible with old
and new behaviours.

Added request_ids attribute to resource object for all the volume,
volume_types, volume_type_access and volume_snapshots APIs by
updating following APIs:

volumes: delete, update, force_delete, reset_state, extend,
migrate_volume, retype, update_readonly_flag, manage, unmanage,
promote, reenable, get_pools, initialize_connection,
terminate_connection, get_encryption_metadata

volume_types: delete
volume_type_access: add_project_access remove_project_access
volume_snapshots: delete and update

Returning list with request_ids as attribute in case of
'delete_metadata' and 'delete_image_metadata' APIs.

These changes are required to return 'request_id' from client to
log request_id mappings of cross projects.

For more details on how request_id will be returned to the caller,
please refer to the approved blueprint [1] discussed with the
cross-project team.
