Today the replication controller defines a PodTemplate which allows it to instantiate multiple pods with identical characteristics.
This is useful but limited. Stateful applications have a need to instantiate multiple instances of a more sophisticated topology
than just a single pod (e.g. they also need Volume definitions). A Template concept would allow a Controller to stamp out multiple
instances of a given Template definition. This capability would be immediately useful to the [PetSet](https://github.com/kubernetes/kubernetes/pull/18016) proposal.

Similarly the [Service Catalog proposal](https://github.com/kubernetes/kubernetes/pull/17543) could leverage template instantiation as a mechanism for claiming service instances.
