These 2 errors are from etcd-client, which mean that the GD2 cannot
connect to the etcd server.
As the errors indicate, it could be because the etcd daemon isn't
running successfully,
or because etcd hasn't successfully connected to its cluster. There
could be more information in the etcd log under
`GD2WORKDIR/log/etcd.log`.

I've faced this issue intermittently, but I've never bothered checking
what caused it yet. I just nuke everything and start again.

Will do it. The whole ReST document is in need of a recheck.
