In case `verify_server_hostname` is set in the configuration, Consul checks the certificate against `server.<datacenter>.<domain>`.
The name suggested by the guide generates errors like the following:
```
2018/10/10 12:42:20 [ERR] consul: Failed to confirm peer status for consul-3: rpc error getting client: failed to get conn: x509: certificate is valid for server.node.consul.labs, localhost, not server.consul.labs. Retrying in 16s...
```
Removing the `node` part from the certificate permits them to work also when that option is set.
* update encryption doc and add guide for creating certificates in consul with cfssl
* add details about CLI and disabling HTTP
* delete $ symbols and add guide elements
* add missing periods and steps heading
