Change service names

[Akrog]

For rolling upgrades/updates we'll need to have multiple instances of Ember-CSI running against the same backend, so we cannot have a fixed name for the StatefulSet and the DaemonSet of each backend, as that would create a conflict in Kubernetes.

The name could either use the hash of the image that's going to be used, some metadata from the image, or the vendor_version that will be reported by Ember-CSI once it has a finer grained vendor_version (embercsi/ember-csi#108).
