T2810: Docs for vpn anyconnect-server

[RasPutinnn]

This documentation describes how to configure AnyConnect-Server on VyOS

[dmbaturin]

Cisco consistently spells it "AnyConnect" in all their publications. I believe we should do the same for the sake of consistency.

Other than this minor issue, this is sure a welcome addition, I'm happy to merge once spelling consistency is fixed.

How about use AnyConnect-compatible server
We need to add a disclaimer about trademarks @dmbaturin

[dmbaturin]

@syncer I'm only talking about capitalization: "AnyConnect-compatible" over "anyconnect-compatible" etc.

Regarding trademarks, I believe we indeed should add a disclaimer somewhere, as a CYA measure.

I'm of the opinion here that we shouldn't say "AnyConnect" at all, except in the documentation of to say "AnyConnect compatible". Similar to what the original https://www.infradead.org/openconnect/ documentation mentions.

Unfortunately, I think the whole documentation for it needs to be refactored AND the underlying code. I think even

set vpn anyconnect ...

Is opening ourselves up to potential future issues.

Moreso since as the above link mentions, OpenConnect works with more than just AnyConnect. And 2), could we even get away with using the name:

set vpn openconnect

Wouldn't ssl-vpn or something be better?
