Cinder API response for group in 'creating' state handled incorrectly
and has_snapshots attribute is not populated. This attribute is checked
during various operations with groups and error is generated if it is
absent. However, this error has no consequences except message in log.
When a created group is in 'creating' state, UpdateRow class is
responsible for retrieving a group data.
Previously UpdateRow.get_data did not populate 'has_snapshots' attribute.
This commit adds a similar logic as IndexView does.
Admin volume groups table has a same problem. UpdateRow class
now inherits UpdateRow from the project table.
