Description of change

Remove unneeded timers from some tests and move others from parallel
testing to sequential testing.

This is to resolve test failures on freebsd10-64 on CI. The failures
are all due to timers firing later than expected. Timers firing later
than they are set for can happen on resource-constrained hosts and is
not a bug.

In general, it may be wise to put tests that depend on timing into
sequential testing rather than parallel testing, as the timing can
be affected by other simultaneously-running test processes.

I ran this change set (with one fewer files moved to sequential, so not quite this change set) through CI six times and there were no failures on freebsd10-64. I did the same with current master and two of the six runs failed with tests involved in this PR. (I'll probably do at least that many again now that it's a PR.)

The changes LGTM.
One minor comment wrt the dgram tests. Due to the unreliable nature of UDP, those tests can be flaky. I would add an interval to send messages until one is received. (it can be done in a separate PR).

Running CI on this over and over to confirm there aren't other timer issues lurking in other tests, I found another timer to be removed in test/parallel/test-tls-server-failed-handshake-emits-clienterror.js. PTAL.

Freebsd failure on last ci was Jenkins disconnect related.

Had to rebase and force push to resolve a merge conflict with master anyway, so let's run CI again!

Additional failing test on FreeBSD is unrelated. Will open a separate PR for it.
