-- Manually starts server maintenance. This command can be useful if an earlier maintenance attempt failed, and the underlying cause of maintenance failure has been resolved. The server will switch to @UNDER_MAINTENANCE@ state, while maintenace is in progress.
--
--
-- Maintenace can only be started for @HEALTHY@ and @UNHEALTHY@ servers. A @InvalidStateException@ is thrown otherwise. A @ResourceNotFoundException@ is thrown when the server does not exist. A @ValidationException@ is raised when parameters of the request are invalid.
