Added support for reflecting "identity" columns, which are now returned as part of the structure returned by :meth:`_reflection.Inspector.get_columns`. When reflecting full :class:`_schema.Table` objects, identity columns will be represented using the :class:`_schema.Identity` construct. Fixed compilation error on oracle for sequence and identity column ``nominvalue`` and ``nomaxvalue`` options that require no space in them. Improved test compatibility with oracle 18. As part of the support for reflecting :class:`_schema.Identity` objects, the method :meth:`_reflection.Inspector.get_columns` no longer returns ``mssql_identity_start`` and ``mssql_identity_increment`` as part of the ``dialect_options``. Use the information in the ``identity`` key instead. The mssql dialect will assume that at least MSSQL 2005 is used. There is no hard exception raised if a previous version is detected, but operations may fail for older versions. Fixes: #5527 Fixes: #5324 Change-Id: If039fe637c46b424499e6bac54a2cbc0dc54cb57
