cinder: Double [DEFAULT]/rpc_response_timeout to 120
Bug #1873234 documents a number of CI failures caused by RPC requests
from c-api to c-vol timing out due to `lvchange` taking longer than the
default rpc_response_timeout of 60 seconds to complete.
While the underlying reason for the slowness should be investigated by
the cinder team a trivial workaround to the fallout created by these
timeouts is to simply double the client RPC timeout used by c-api,
allowing c-vol to return and overall the request to succeed.
