Olof Johansson 5393dc1929 Fix various pylint warnings
None of these were any real problems, but easier to spot real issues if pylint
is a bit quieter. Apart from the pylint overrides being sprinkled over the code
base, this commit also fixes occurences of the following issues:

 - logging-not-lazy
 - logging-format-interpolation
 - unused-import
 - unused-variable
