Figure out why test_autofocus_coarse hangs

[wtgee]

The test_observatory.py test_autofocus_coarse is hanging on almost all branches some of the time. Often a restart of the test will fix it. Need to figure out what process is causing the problem.

Setting plots=False in the test files seems to do the trick. Still testing out some changes.

Note: I didn't figure out why this was happening, I just set it to skip for certain tests. Still need to figure out why so should probably leave open.

That is odd. Haven't had issues with this in the past. I have been seeing intermittent test failures in the Arduino tests, though.

This change to disable focus plots in the tests has broken the autofocus tests in my pyro-cameras branch as there I had expanded the tests to check for the presence of the plot files while I was working on the copying of files from remote cameras. I've re-enabled plotting in my branch for now, will keep an eye out for hanging tests.

Something about the arduino simulator definitely does wacky things to our coverage.

It definitely could have been the result of my refactor and/or subsequent barrage of PRs.
