ci: remove highest firing golanglint-ci

Created by: keegancsmith

This is an attempt to improve the signal of golanglint-ci. It removes the highest firing lints in our codebase. We should probably remove more and stick to just lints that find bugs (like staticcheck). This is a first step.

Ran the following shell command and removed all checks with 50 or more complaints.

golangci-lint run | egrep -o '\([a-z]*\)$' | sort | uniq -c | sort -n
