[Lint] Cleanup code to pass PyLint Warning category

 Selected Warning messages disabled in pylintrc:
  * unused-argument: Quite a large and disruptive change if enabled.
  * broad-except: Most required in-depth investigation to determine type.
  * fixme: Not important
  * protected-access: Complicated to fix
  * import-error: Too many false-positives
  * unidiomatic-typecheck: Should be fixed in the next round of checks.
  * unused-variable: Again large and disruptive changes.
  * global-statement: Most usage is required.
  * attribute-defined-outside-init: Should be fixed in next round of checks.
  * arguments-differ: Possible false-positives, needs revisited.
  * no-init, non-parent-init-called, super-init-not-called: False-positives?
  * signature-differs: False-positives?
