separate machine_providerconfig and cluster_provider config

[Lion-Wei]

OpenstackProviderConfig can be separated into cluster scope and machine scope.

Based on the skeleton repo maybe we should split the machine and cluster actuators into separate packages as well?

[Lion-Wei]

For now we don't have cluster actuators, but sure, when we add cluster actuators, we need consider separate then in two packages.

Actuators already separated by #94.

I am currently working on an implementation of the cluster actuator which needs its own ProviderSpec. See #106.
