- Instead of EnsureBridge
- Adds ipset.ExistEntry method
- Refactor ipset method names Exist <-> EntryExists
- Turn on iptable-refresh by default (10s)
- Adds a test that checks iptables are refreshed, check EXPOSE recovers
As ipset.New(...) can be called by two processes (weaver and weave-npc)
at the same time, there is a possibility for a race when they both
check the comment support. To prevent the race, we append a random
nonce to the test ipset name.
