Configurable cache key

Welcome

• Yes, I understand that the GitHub action repository is not the repository of golangci-lint itself.
• Yes, I've searched similar issues on GitHub and didn't find any.

Your feature request related to a problem? Please describe.

I would like to include the values of GOARCH, GOARM, GOOS and the --build-tags argument into the cache key which is not possible because the cache key is hardcoded.

Describe the solution you'd like.

A cache-key option to define a custom cache key.

Describe alternatives you've considered.

None

Additional context.

I think I'll be using actions/cache directly to have full control over that cache, but other users might be interested in such an option.

Golangci-lint should not be used from a platform to target another platform (GOOS, GOARCH, ...)

Golangci-lint is not Go.

You can influence the analysis by playing with the GOOS or GOARCH but golangci-lint is compiled for a specific OS, so some pieces, related to the other OS, can be missing and lead to unexpected behavior.
