Ceph » Orchestrator

When using cephadm and specs files, we can set configuration for the services, like
```
service_type: rgw
service_id: realm.zone
placement:
hosts:
- host1
- host2
- host3
config:
param_1: val_1
...
param_N: val_N
```

This works preatty well. Except when we want to remove some configuration, like the param_X with value_X, it stays on the ceph configuration db. Would some option here to remove it from the db to revert to it's natural default be relevant?
