* add ability to set issue severity for out formats that support it based on severity rules
* fix lint issues
* change log child name
* code climate omit severity if empty
* add tests for severity rules, add support for case sensitive rules, fix lint issues, better doc comments, share processor test
* deduplicated rule logic into a base rule that can be used by multiple rule types, moved severity config to it's own parent key named severity, reduced size of NewRunner function to make it easier to read
* put validate function under base rule struct
* better validation error wording
* add Fingerprint and Description methods to Issue struct, made codeclimate reporter easier to read, checkstyle output is now pretty printed
1. Rename in a backward compatible way
2. Remove gosec default exclude list because gosec is already disabled
by default.
3. Warn about unmatched linter names in //nolint directives
4. Process linter names in //nolint directives in upper case
5. Disable gosec for golangci-lint in .golangci.yml
We skip all issues from autogenerated files.
Also reuse AST parsing for nolint and autogenerated exclude processors:
decrease processing time on golang source code from 3s to 800ms.
As observed in #30, there's tools out there that don't comply 100% with
the referenced golang convention.
With this change, golangci-lint will skip some more of those generated
files.
