SPIKE: protocols compatible with mobile

[zolia]

In order to deliver mysterium VPN on mobile platforms
As a developer
I want to have well supported VPN protocols on iOS and Android

Investigate existing mobile supported VPN protocols and suggest next protocol to implement on a node.
Investigate if they can be integrated (especially authorisation) with our framework.
