Right now when looking at a list of Boulder CI test results, they all
say:
boulder_ci_tests (go_1.17_2021-...
Which is not very informative as to which type of test failed. This
shortens the test name to "ci", and also changes the invoked command so
more of it fits on the screen. That involves adding two new scripts,
t.sh and tn.sh, which each run `docker-compose run ... test.sh`. tn.sh
runs it with the appropriate flags to use config-next.
