faft: A workaround to wait for client RPC server start-up
We found that the RPC call retrial doesn't work all the time and causes
timeout error happened. It breaks FAFT most of the time. So add this delay
to wait the client RPC server start-up as a work-around. This is a
temporary fix.
BUG=chrome-os-partner:16037
TEST=run a FAFT test and pass.
