IncompatibleObjectVersion should also mention, the supported version

[Sudipta Biswas]

The IncompatibleObjectVersion class in nova/exception.py doesn't mention the supported version.
Currently the information presented is only with respect to the remote object version being incompatible:

Version %(objver)s of %(objname)s is not supported.

The additional information should include the supported version number as well.
This would atleast give an idea to the user on the supported level on the controller/conductor APIs.

we use
322 raise exception.IncompatibleObjectVersion(objname=objname,
323 objver=objver,
324 supported=latest_ver)

but exception shows

1523 class IncompatibleObjectVersion(NovaException):
1524 msg_fmt = _('Version %(objver)s of %(objname)s is not supported')

    Include supported version information

    Currently the IncompatibleObjectVersion class doesn't include
    the information of the supported version. This would atleast give
    an idea to the operator on the maximum supported version on the
    controller/conductor APIs.

    This patch will print the maximum supported version information
    in the exception log.
