[FEATURE] Use goreleaser to automatically generate a homebrew package

[alexlovelltroy]

We want to make this software as accessible as possible and potentially even useful outside an OpenCHAMI cluster.

https://medium.com/@ben.lafferty/deploying-go-cli-applications-316e9cca16a4 describes how to build and release homebrew formulae for CLIs.

We should consider adding this functionality to Magellan.
