Bryan Boreham e8fcd21baa Retry IP allocator claims 
It may be that we cannot talk to a peer straight away, so allow claims
to be retried a few times before giving up.

Bryan Boreham 44f91950cb Improve logging of ring merge 
Turn some Sprint() calls into `%v` in the outer format string.
Remove one debug log line on duplicate token, since that info is already logged.

Add an Info log line when we accept another peer's token, since that
should be a rare event, and it's important if we've made a mistake.

Bryan Boreham d2f0287fa3 Handle range wrap-around when checking for allocations 
Ring wraps around at zero but Space doesn't know about this, so we
have to normalise ranges coming out of Ring.  In turn we may need to
split one range into two, across the end of the Ring.

Martynas Pumputis 79f77f94f4 ipam: Do not deref nil in GET /ipinfo/tracker if tracker doesn't exist 
In some cases, we do not create any IPAM tracker, which leads

Bryan Boreham 39ac1a0037 Collect existing weave addresses at start-up, to avoid a race when 
doing it from the script

Note we need to run weaver in the host pid namespace, so it can search
for existing container IPs. Also now we are firing off sub-processes
it's better to not be PID 1 so Linux doesn't expect us to reap zombies.
