Feature: trigger a rollout/rolling-update for deployments and replication controllers

[blakebarnett]

I was thinking this could be done using an annotation on a deployment or RC, something like:

  annotations:
    konfd.io/track-configmaps: foo, blah, blerg 
    konfd.io/track-secrets: asdf

Or possibly by inspecting the resource to find any references to configmap/secret volumes or field refs.

  annotations:
    konfd.io/update-on-changes: true 

I imagine this could eventually apply to jobs, daemonsets, statefulsets, etc. also.

@blakebarnett I love this idea, let me think about it a bit more and flush out a design.
