Alpine image variant

[probablykasper]

Would be great to have an Alpine CouchDB Docker image. Alpine is usually the go-to for lightweight Docker images.

For reference, here's a repo of a CouchDB Docker image built with Alpine: https://github.com/smizy/docker-couchdb

The general trend for our images has been to push the build steps over into our packaging repo, then have the Docker container only install the prebuilt package for simplicity of maintenance.

We'd love to have someone join us to work on packaging for Alpine if they're interested.

@wohali Should I open this issue in couchdb-pkg in that case?

[wohali]

@probablykasper Only if you're intending to work on it :)

@wohali Then I'll pass for now because it seemed a bit difficult to get all of the dependencies
