Configuration for xp016 does not include node9

Assuming a Nightking spawned with AMI `Interchain Nightking image 1580152443 (ami-0d79ba53d7354069c)` in region `eu-central-1`, it seems that experiment `/etc/experiments/xp016` does not include any configuration for node9. The folder for this node is simply missing.

If we look in the `genesis.json` file, at the entry corresponding to node 9, we find the following:

```
{
"address": "793875B4C4F79DB465050E809599B2271A9CC0A5",
"pub_key": {
"type": "tendermint/PubKeyEd25519",
"value": "bsrUwx4buSSPHy3qpnfYbeYsHkK77W9kSuZDSJQrzWE="
},
"power": "1",
"name": "node9"
},
```

The address here, as well as the value field are taken from the seed node's configuration file. Using this experiment might lead to a deployment where nodes do not correctly connect to each other.
