TrigUpgradeTest: Remove OutputLevel settings and python cleanup
- Remove almost all explicit settings of
OutputLevel
except those that are required in the reference file comparison - Enable
flake8
unit test for python modules and related fixes - Explicitly specify
nopost.sh
for tests without references
This is touching a large amount of python files but the changes are mostly cosmetic (removing unused imports/variables, indentation, etc.). Making the python files here flake8-compliant will also make the future migration of this code into TriggerMenuMT easier (where flake8-compliance is already enforced).
Some of the tests are still producing a lot of DEBUG output but this needs to be fixed outside of this package and will be done as a separate MR.
