Updates for python3.8

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.
