Improve the documentation about openvpn-admin-plus HOT 3 CLOSED

@melakhvision

Fair point, I'll add some detail on those.

The first two are EasyRSA values intended to improve the cryptographic strength of generated keys and certificates.

ORG = Organization
You can use your company name or make something up if you don't have one.

OU = Organizational Unit
A typical value here would be IT (for Information Technology), or again you can make something up.

The second two are PiVPN values, which include the the unique ID PiVPN uses in creating your server certificate. If your look at the /etc/openvpn/server.conf file generated by PiVPN, you'll see it in the cert and key directives in the file. That long string, which starts with the hostname of your OpenVPN server and ends with a .crt or .key is what you want to use.

So on my test system:

PIVPN_SERVER = raspberrypi10_ca8554c5-6025-442f-9d06-25a5cab85a3c

PIVPN_CONF = server.conf (which is the default name created by PiVPN)

I added some comments to the docker-compose, and I'll add some to the README as well:

I added the same commented environment section to the README, so I think we should be covered. I noticed PIVPN_SERVER and PIVPN_CONF were already discussed there, but of course it doesn't hurt to have some things described multiple times.

ORG and OU definitely needed clarification though. Those values used to be requested during a PiVPN script install of OpenVPN, but I don't think that's the case anymore. They're still used to improve cryptography when available, AFAIK.

I'm closing this one out, but feel free to re-open if needed. Cheers.
