[autotest] RPC logging server

frontend.afe.rpc_handler is not logging RPC logs correctly
due to multi apache processes.
We should have a daemon that receives log records from the
apache processes and writes them in a chronological order.

BUG=chromium:490897
TEST=Run dummy suite on local machine.
DEPLOY=apache
