Yeah, this happens all the time. This kind of bugfix is generally not
versioned.

Allow the caller to restrict the set of interfaces that announces are
sent on. The default is still to send on all interfaces.
e.g.
{ "execute": "announce-self", "arguments": { "initial": 50, "max": 550,
"rounds": 5, "step": 50, "interfaces": ["vn2","vn1"] } }

Laine asked for some extra features on the network announce support;
this is the first one of them.
It allows you to send an announce on a subset of the interfaces.
Note since we've still only got one timer, if you start one announce

Add the optional interface list to the HMP command.
i.e.
All interfaces
announce_self
Just the named interfaces:
announce_self vn1,vn2
