Adds handler to capture external exits of processes, and tests to verify this is indeed happening. Problem: I don't know how to silence crash reports in this case. When I run the tests, I can see the crash reports I added, but I would like to silence them in tests. ct_helper:ignore() doesn't seem to cut it the way I use it, which is probably wrong. I see on the console: Testing ninenines.cowboy.metrics_SUITE: Starting test, 96 test cases =ERROR REPORT==== 23-Apr-2021::11:22:09 === Ranch listener http, connection process <0.266.0>, stream 1 had its request process <0.275.0> exit with reason external_exit which we probably want to silence but I'm not sure how. Help?
