Addressing bandit feedback

Addressing feedback recorded in gitlab-org/gitlab#376025 (closed). While looking into these patterns, I went ahead and eliminated some more FP patterns.

Approach:

1. Refined B610 to eliminate FP patterns
2. We did not modify B105, B106 as they seem reasonable
3. Refined B108 to match the original patterns more accurately
4. Use generic pattern matching for B110, B112 to support exception chains
5. Broke down the single rule B313, B314, B315, B316, B317, B318, B319, B320, B405, B406, B407, B408, B409, B410 into smaller pieces
6. Reduce the rules; the initial rules-set was based on a rule-set provided by r2c where we focused more on coverage than actual parity. We have to trim down some of the rules to match more accurately what bandit would return.
