If the maximum client version is higher than the maximum server version,
but the server version is otherwise valid, an UnsupportedVersion
exception is thrown. This bug fixes this issue by downgrading the
requested version, during API version discovery, from the maximum
client version to the maximum server version. The maximum server version
must be supported by the client. If all conditions are properly met the
client will continue to use the maximum server version for the remainder
of the request.
In order to log that the client version is being downgraded to match
the server version, when using the --debug flag, it was necessary to
update the logging configuration. Logging can now be used anywhere in
manilaclient as needed.
