Support wireguard keepalives

[theblazehen]

Nodes behind firewalls can sometimes lose connection. Supporting PersistentKeepalive would help with that

Using Wireguard with nodes behind a NAT, I can't switch to Wesher while persistent-keepalive isn't supported because external servers are unable to connect to nodes behind a NAT.

@KillianKemps I've been using one of the forks with it added, and it works great

@theblazehen Can you give me the link to one of those forks with keepalive?

[theblazehen]

@KillianKemps https://github.com/USA-RedDragon/wesher has both keepalive and advertiseaddr support. Recommend using advertiseaddr in addition to the keepalive

@theblazehen Thanks for the link!
