Azure has its own etcd configuration

Browse Source 
Other than two lines, it's identical to AWS's etcd configuration.

I've also updated the instructions for configuring it.

Let's fire up etcd:
```shell
sudo systemctl daemon-reload
sudo systemctl enable etcd
sudo systemctl stop etcd
sudo systemctl start etcd
sudo journalctl -xefu etcd # look for any errors on startup
```
If the messages look innocuous (ignore "serving client traffic insecurely; this
is strongly discouraged!"), then check the cluster:
```shell
etcdctl member list # "8e9e05c52164694d, started, default, http://localhost:2380, http://localhost:2379, false"
```
