EAP-RADIUS support implemented

[GurliGebis]

Hey,

I have been playing around with a test setup of opnsense, but noticed that it is not currently possible to use EAP-RADIUS.

So, I went ahead and implemented it.
It is split across two pull requests:

https://github.com/opnsense/tools/pull/43
https://github.com/opnsense/core/pull/1342

I have tested it on my own setup, and it seems to be working just fine (Windows 10 clients connecting in).
Please note, that it has been several years since I have touched anything PHP related (moved to C#, since that is my day job).

The following text strings has been added, but I'm not sure how add the to the gettext dictionary for translation - if someone can tell me how to do that, I'll do it and add another commit/pullrequest for that.

Is it possible to get it into 17.1, or are we too close to release for that?

Thanks

Note to self, the text strings to translate is:

"You must enter both RADIUS server and secret to use EAP-RADIUS."
"RADIUS Server"
"Input your RADIUS server IP."
"RADIUS Secret"
"Input your RADIUS secret."
