Add metric for remaining lifetime of certificates authenticating requests

fixes #50778

When incoming requests to the API server are authenticated by a certificate, the expiration of the certificate can affect the validity of the authentication. With auto rotation of certificates, which is starting with kubelet certificates, the goal is to use shorter lifetimes and let the kubelet renew the certificate as desired. Monitoring certificates which are approaching expiration and not renewing would be an early warning sign that nodes are about to stop participating in the cluster.

**Release note**:

```release-note
Add new Prometheus metric that monitors the remaining lifetime of certificates used to authenticate requests to the API server.

Remove packages which aren't relied on by heapster anymore.

**What this PR does / why we need it**:
Do the TODO:

// on this package.  This will allow us to start splitting packages, but will force
// heapster to update on their next kube rebase.
```

These packages aren't relied on by heapster anymore. This PR removes them. This is a followup of #48410.

e2e test for local storage mount point

**What this PR does / why we need it**:

We discovered that kubernetes can treat local directories and actual mountpoints differently. For example, https://github.com/kubernetes/kubernetes/issues/48331. The current local storage e2e tests use directories.

This PR introduces a test that creates a tmpfs and mounts it, and runs one of the local storage e2e tests.

**Which issue this PR fixes**: fixes https://github.com/kubernetes/kubernetes/issues/49126

**Special notes for your reviewer**:

I cherrypicked PR https://github.com/kubernetes/kubernetes/pull/50177, since local storage e2e tests are broken in master on 2017-08-08 due to "no such host" error. This PR replaces NodeExec with SSH commands.

You can run the tests using the following commands:
``` 
$ NUM_NODES=1 KUBE_FEATURE_GATES="PersistentLocalVolumes=true" go run hack/e2e.go -- -v --up
$ go run hack/e2e.go -- -v --test --test_args="--ginkgo.focus=\[Feature:LocalPersistentVolumes\]"
```

Here are the summary of results from my test run:
```
Ran 9 of 651 Specs in 387.905 seconds
SUCCESS! -- 9 Passed | 0 Failed | 0 Pending | 642 Skipped PASS

Ginkgo ran 1 suite in 6m29.369318483s
