Add logging to TimeoutHandler

The reconcile tests were causing panics or tripping race detection
because the timeout handler was using the *testing.T methods after the
test was already marked done.
The solution is to use loggers that are not tied to the testing
framework. The downside is that you may see logs from prior tests
intermixed but that is usually just the one associated with stopping the
timeout.
