Testing replication between two appliances in different regions

This uses the single_appliance information in cfme_data.yaml to provision appliances. Currently the version specified in cfme_data.yaml is "version1", so my cfme_data.local.yaml adds a valid version number so it is able to provision:

```YAML
appliance_provisioning:
    provider: vsphere55
    single_appliance:
        name: single1
        version: 5.2.3.2
```
