We should do verbose logging for each state transition.

The CONNECTING->CONNECTED state transition is hidden in this diff, but we should assert the previous state where we can.

I have a PR that extracts this into a method, I'll add the logging though

Do these short 1 second timeouts ever cause flakiness? If not, I'm impressed.

There were one or two flaky tests in java but I don't think they were ever related to these timeouts.
And actually, yesterday I was looking into them and there is a pretty good reason these never trigger. We can talk about it later today.

The hub could be already-started here too, right? Maybe log the current state.

I'm limiting this change to just adding the
CONNECTINGstate and modifying a couple things so it works as expected.Part 2 will fix things like calling stop while in the middle of start, but I want to clean up the code a bit before doing that, so I'm planning on making a "clean up" PR before doing Part 2.
Easier to review if you turn off whitespace changes.
Progress towards #23291
