Fix dependencies for PreConfig/PostConfig resources

We have a circular dependency errror since

https://review.openstack.org/#/c/452734/ landed.

This adjusts the dependencies to ensure we run pre-config before
the first puppet deploy step, and removes the duplicate declaration
of the ControllerPostConfig resource.  Also we ensure the first
container step always depends on the same step puppet deploy.
