Allow scheduler manager NoValidHost exception to pass over RPC

[Hans Lindgren]

Calls to scheduler.manager.select_hosts are expected to throw NoValidHost exceptions if no hosts match such requests. For the exception to be passed over RPC, the method must be decorated with:

@rpc_common.client_exceptions(exception.NoValidHost)
