MonkeyPatch time.sleep in unit tests to avoid wait

There's no need to wait real world seconds when there are no real
world servers at the other end of these API calls. We still do wait a
little bit of time, in case there is some reliance on actually having
called the real time.sleep, but this should feed up test running in
a loop quite a bit.

Also lowering timeout on rebuild_server as it unnecessarily sleeps
for 1 second.
