Subject: [PATCH] Parametrize alpine version in Dockerfile

Set the version of the Alpine base container as an argument with a default value to allow easy substitution without the need to modify the upstream file. This can be leveraged both from docker command line (`docker build --build-arg ALPINE_VERSION=<version> <acmesh_github_url>`) and from docker-compose files.
