(Only valid once #324 is merged)
Deleting the 2nd peer in a 2 node cluster will leave the 1st node unresponsive. This happens when using the embedded elastic store.

This happens because the etcd instance is left without quorum to operate when the 2nd peer leaves. With 3 or more peers, the etcd cluster still has quorum and can continue to serve requests.

Solving this requires changes to elasticetcd and the deletepeer code, to introduce special cases for handling deletes in a 2node cluster.
