[#62626870] Remove Query API record format code

The Query API can return data about our entity types in three formats: records, idrecords, and references.

Only 'records' format (the default) is useful to us - the other formats are effectively redundant.

This PR removes support for specifying the :format option to the API, removes the --format option from vcloud-query, and removes reference to record formats from vcloud-query output.
