MXS-2273 Make schemarouter honour BEING_DRAINED bit

Browse Source 
The schema router now deals with the being drained bit the same way
it deals with the maintenance bit, that is, a server being drained will
simply be ignored.

TODO: This behaviour needs to be document.
TODO: It seems the schema router simply ignores the maintenance bit
      once a connection has been establisdhed.
