Docker Secret Support

[reggie-mcmurtrey]

It would be great if we had support for docker secrets. The following two environment variables would allow this:
WG_ADMIN_PASSWORD_FILE
WG_WIREGUARD_PRIVATE_KEY_FILE

If they aren't NULL they would override the normal variables and you could read the values from the files they point too..

Anyway, thanks for the great work.

If this is still wanted. I to would recommend opening a ticket with https://github.com/alecthomas/kong (or kingpin but it gets no development and Kong is a recommendation) to support docker secret variables. Easier than trying to do a one off per app.

Either that or find some entry point scripts that will translate them if set
