Feature Request: Add Ability to Set "cache dir" in .erb-lint.yml

[klondikemarlen]

I'd love to keep all the config in one place.
I'm already using the glob: option, and I'd love to be able to set the cache_dir as well.

e.g.
Instead of running bundle exec erblint --lint-all --cache --cache-dir tmp/xxx
I'd love to be able to set the cache and cache-dir options in the .erb-lint.yml config file.

Just to unnecessarily pile on, how bout a cache section in the config?

glob: ALLTHETHINGS
cache:
  enabled: true
  dir: cachey-mc-erblint-cache
linters: [] # linting overrated

I created a implementation for this in #351. My only concern with this is that currently the linter does not support running the cache with autocorrections, so if the option is set the users are not going to be able to autocorrect the linters because the cache option will not let them do it.

@domingo2000 That's awesome! Maybe just make it warn that cache is disabled when running with auto-correct?
i.e
"Cached disabled due to "autocorrect" option, will re-activate once no longer using "autocorrect" option."?
