ded4414ef4 Respect the -D flag 
It looks like edfbffb85f caused the
OVPN_DNS variable to start being ignored, meaning the -D flag was a
no-op.

ovpn_copy_server_files: Copy openvpn.conf instead of symlinking locally. 
Symlinked files can be resolved by rsync when using the configuration on remote
servers but for local testing having the actual file is beneficial.

ovpn_copy_server_files: Ensure that no other keys then the one for the server is present. 
When creating a multi-server setup I used a partly copied, partly
symlinked directory structure for the different servers after creating a
certificate for each server with `easyrsa build-server-full`. In that
process I also copied the `server` directory.
The rsync command does not delete files which are not excluded so it
included the correct server key and the original one which can be a
security risk.

34d9601e6e ovpn_run: Assume /etc/openvpn is read-only 
* Systemd service currently marks the mount as read-only, and this is
  regarded as good practice for server/daemon only operation.
* Don't create /etc/openvpn/ccd as the mount may be read-only.
* Append the client-config-dir command line argument if it is found to
  avoid mkdir operation.
* Mount can easily be modified using a different docker run line with
  ":ro" on the volume mount.

6aca273d89 getclient: Use openssl to prune comments

  prune it.

Optimized ovpn_copy_server_files script. No need to copy the config files. 
* rsync can copy the actual files.
* This change makes it easier to modifier the configuration and sync it
  to the server. You only have to execute the ovpn_copy_server_files
  once.

852d404c12 env: Re-work environment code 
* Instead of storing just a server_url which was necessary to
  regenerate the OpenVPN configs, instead store an env file.
* Move all the env parsing to `ovpn_genconfig` so that it can be re-run
  from genconfig instead of from `ovpn_init`.
* Remove all the parsing and env defaults except for genconfig.

NOTE: This breaks the older config method, uesrs will need to re-run
genconfig with an arg[1] as the previous server_url, this will create
the necessary env file the rest of the tools expect.

Example recovery for legacy users:

    host$ docker run --rm -it kylemanna/openvpn bash -l
    container# ovpn_genconfig $(cat /etc/openvpn/server_url)
