Aim of this PullRequest is to add several new pod metrics:
- kube_pod_deleted: Unix deletion timestamp
- kube_pod_status_reason: The pod status reasons (NodeLost, Evicted)
These new metrics can be used to determine the `pod.status.phase`
displayed by `kubectl`: Running, Terminated, Unknown…
It will allow removing the `kubectl` display logic added previously
to compute the “Unknown” phase.

- To allow other external Stores, remove the `FamilyByteSlicer` interface
and give access directly to `metric.Family`.
- Move functions present in `pkg/metric/generator.go` to a dedicated package
`generator` in `pkg/metric_generator/generator.go`.

Report pod_restart_policy{...,type="Always|OnFailure|Never"} 1 for the
pod.spec.restartPolicy which allows an admin to know how many batch vs
service workload pods are running on the cluster.
Since the removal of collector, this introduces both the concept of the
store and the resources instead of collectors that the user passes in.
The user facing logs and flags were not changed as that would be a
regression.
