Ability to use volumes within deployed apps

I've recently needed the ability to mount a volume from the host into a pod. It actually made me question the use of deis for this particular app and if I should just use deployments instead. It would be awesome if we could make a persistentvolumeclaim or use a regular volume mount.

Copied from original issue: deis/controller#1111

Would also be interested in this. Often times I find myself questioning whether I should write my own deployment spec or hot-patch the DeisWF deployment after updating the image and/or configuration.

We won't allow host mounts through the CLI/API due to the implied security issues that would provide. Arbitrary users could mount in the host docker socket into their app and have cluster-level access. Storage providers via persistent volume claims will be provided via deis/deis#231.

Also see https://github.com/kubernetes-incubator/service-catalog and the #sig-service-catalog channel on Kubernetes' Slack channel for active development on this front.
