Merge branch 'atomaka/refactor/metric-clean-up' into 'master'

Clean up metric_fu violations

Clean up many of our violations. Most of these are meaningless fixes that do not resolve the actual issue.  For example, we use delegate to remove the law of demeter violations, but that doesn't really resolve the issue.  We pass some more stuff though and that's good enough for now.
