Add instance group manager bulk per instance config resource.

[pjotrekk]

This PR introduces a new virtual resource for instance group managers: BulkPerInstanceConfig.

In this version it accepts only instance names which makes it possible to call instanceGroupManagers.CreateInstances with more than 1 instance in a single call. So far it was limited to a single PerInstanceConfig.

BulkPerInstanceConfig is immutable and on each modification it will call instanceGroupManagers.DeleteInstances on Destroy and instanceGroupManagers.CreateInstances on Create. Thanks to that Update is not implemented.

instance group manager should be configured to ignore target_size changes, as BulkPerInstanceConfig modifies this value.

I think we should disable importing

Sorry, couldn't remove it after all because I'd have to delete the whole identity object where igm is set. Maybe it's ok to remove it but I'm not able to finish it before vacation
