Remove sleep(1) call from launcher

The reason we thought it was there for is no longer valid: the sockets
are created in the main thread so by the time the objects are created
it's safe to start connecting to the services. I don't see other
reason to have it so I removed it after testing both locally and on
GCE.

Test: run local & GCE
