Add a new configuration parameter rpc_response_max_timeout

Browse Source 
A new parameter rpc_response_max_timeout is added and registered into
neutron.conf.

The rpc_response_max_timeout plays a role of the ceiling of timeout
seconds when waiting for the response of a remote rpc server.

During an RPC call, the waiting time starts from the existing parameter
rpc_response_timeout(default 60s) and doubled each time until it reaches
the ceiling which is currently set as 10 times rpc_response_timeout.
It seems to be less flexible since user cannot directly change the
ceiling value unless he/she changes the rpc_response_timeout.
By adding rpc_response_max_timeout, user can now modify it without
changing any other parameters.
