Added support for "CREATE SEQUENCE" and full :class:`.Sequence` support for Microsoft SQL Server. This removes the deprecated feature of using :class:`.Sequence` objects to manipulate IDENTITY characteristics which should now be performed using ``mssql_identity_start`` and ``mssql_identity_increment`` as documented at :ref:`mssql_identity`. The change includes a new parameter :paramref:`.Sequence.data_type` to accommodate SQL Server's choice of datatype, which for that backend includes INTEGER and BIGINT. The default starting value for SQL Server's version of :class:`.Sequence` has been set at 1; this default is now emitted within the CREATE SEQUENCE DDL for all backends.
