Currently the update_traces_checksum script prints a label verification
request with a line that is 167 characters long.
Split the long line to make it more readable. Update the flake8
configuration to enforce a maximum line length of 159 characters to ensure
consistency.

Currently the ci scripts and tests don't have any linting checks. Add
.flake8 linting to start adding some consistency to the scripts. Ignore
most of the existing errors until they can be addressed on an individual
basis.
