Unit test logging

Tempest used to have logging.conf sample which included
stress logging, it was removed from tempest adding more
up date version here.

Also test cases can fail with an assert method
which considered failure not error.

Having the test case exceptions logged.

Stop overriding the working logger name,
as no other action does such override.
