`updatePeersFromMaster` is a misnomer as it does not actually query master
until the parameter is true or the TTL has expired (which I have increased to
60 seconds). MOST of the time it is a cheap operation. So I am not sure whats
best here.
I am totally open to more suggestions. How about keeping it `getPeers` with
param name as `forceUpdateFromMaster`?
