Summon as an Alpine package

[Jishin85]

Is your feature request related to a problem? Please describe

It's quite common to block external access, and whitelist Alpine packages, inside Kubernetes/OpenShift environments which causes a problem to run online installation scripts or retrieve Summon directly from within applications in the platforms, or even inside Dockerfiles.

Describe the solution you would like

Summon as an Alpine package would solve this problem, as a simple apt-get install summon would simplify its retrieval and installation. https://wiki.alpinelinux.org/wiki/Creating_an_Alpine_package

Describe alternatives you have considered

Providing an Alpine image with Summon pre-installed, which is not as efficient.

Hi @Jishin85. Thank you for creating the issue. I'm in agreement, an alpine package would be very useful.

We're shifting our release build automation from our own scripts to using Goreleaser. In order for us to support the alpine package I believe it should only require configuring nfpm in Goreleaser.

I think we can move things along so that the shift to using Goreleaser is complete in the coming week. Most of the configuration is in place, it just needs to be connected to the build pipeline. From then we can configure nfpm and we should be able to get the build generating the alpine package.

Please note that the project is open to contribution so feel free to get things started.
