Periodic tag

release: v2.0.0

* Primary highlight is the switch from Debian Jessie to Alpine 3.2.
* This results in a smaller image and security updates seem to arrive faster.

ovpn_copy_server_files: Use short flags with rm

* The busybox tool in the alpine distro doesn't support long flags.

Officially release v1.0 now that Debian 8 (Jessie) has been released.

Dockerfile: Shallow clone EasyRSA v3

* Do a shallow clone for a smaller checkout
* Condense multiple run lines to a single RUN line for a flatter image.

Dockerfile: Set WORKDIR to /etc/openvpn

* Set WORKDIR to simply admin when I run cmd `bash`
* Add comment on port
