With the move to the Victoria job template in
https://review.opendev.org/#/c/722681/, the py37 jobs no
longer get run, so the check and gate job entries can
be removed.
Added a keepalived py38 KillFilter line to match the py36
and py37 ones.
Also updated TESTING.rst to use py38 in all examples.

Since it's no longer supported past Train, lets stop
running the tests.
Updated docs and made some pep8 code tweaks as well.
