Add Goreleaser support for releases and homebrew

[rothgar]

WHAT

This adds a config for goreleaser to manually create releases via goreleaser release and also automatically via github actions when a new tag is pushed. I have an example in my fork and tap repo. brew install rothgar/tap/kubecolor works.

You'll need to create a github repo called dty1er/homebrew-tap/ and you'll need to create a GITHUB_TOKEN with access to push into that repo. You can read more about it here https://docs.github.com/en/free-pro-team@latest/actions/reference/authentication-in-a-workflow#using-the-github_token-in-a-workflow

You can create the token at https://github.com/settings/tokens It should only need repo access. If you want to use goreleaser to publish .rpm and .deb packages or docker containers you can also add package access.

You should make sure the token is set up in the repo settings as GITHUB_TOKEN so goreleaser can use it automatically.

Let me know if you run into problems or have questions. 👍

WHY

So releases are automatic and brew install works

@rogh

Why do we need to do Docker login?

[rothgar]

oh woops, that was from another project. You don't. It's only if you want to create container images and push them to a registry. I'll remove.

Thank you!

I tried brew install dty1er/tap/kubecolor after removed current kubecolor under $GOPATH/bin.

~  $ type kubecolor
kubecolor is hashed (/usr/local/bin/kubecolor)

~  $ brew list kubecolor
/usr/local/Cellar/kubecolor/0.0.7/bin/kubecolor

~  $ brew info kubecolor
dty1er/tap/kubecolor: stable 0.0.7
