Fix #324, relates #314 1. Update gocritic to the latest version 2. Use proper gocritic checkers repo, old repo was archived 3. Get enabled by default gocritic checks in sync with go-critic: don't enable performance, experimental and opinionated checks by default 4. Support of `enabled-tags` options for gocritic 5. Enable almost all gocritic checks for the project 6. Make rich debugging for gocritic 7. Meticulously validate gocritic checks config
