controller: support perma-failed deployments

Browse Source 
This commit adds support for failing deployments based on a timeout
parameter defined in the spec. If there is no progress for the amount
of time defined as progressDeadlineSeconds then the deployment will be
marked as failed by adding a condition with a ProgressDeadlineExceeded
reason in it. Progress in the context of a deployment means the creation
or adoption of a new replica set, scaling up new pods, and scaling down
old pods.
