A while back, I reworked logging and in order to get tests to make assertions on things that were logged, I wrote a caplogpp test fixture which tweaks the "propagate" value on loggers.

Turns out that's all set up wrong and we shouldn't need to have a caplogpp at all.

This bug covers reworking the logging configuration:

1. only the root logger specifies a handler
2. the root logger sets the level to WARNING
3. non-root loggers set propagate=True
4. remove caplogpp (pretty sure we can remove it at this point)

I redid configuration for Antenna recently and in the process of doing that, I think I addressed items 1, 2, and 3. We still have item 4 to do.

willkg merged PR #791: "bug 1669981: remove caplogpp" in 4c894ea.

I deployed this to prod in bug #1757737. Marking as FIXED.
