Store labels and fields with object
We are already computing labels and fields before putting objects in watchcache.
And my tests show this is `PodToSelectableFields` is responsible for ~10% of memory allocations.
This PR is supposed to fix that - let's double check by running kubemark-big on it.

Add bound/unbound pv/pvc volume metrics
**What this PR does / why we need it**:
Fix two bugs in bound/unbound pv/pvc volumes metric e2e test:
1. Check `HasRegisteredMaster` in `BeforeEach` instead of each tests because we will grab the metrics in `BeforeEach`
2. Fix `calculateRelativeValues` bug, if there are other PV/PVC exist in the cluster, `calculateRelativeValues` will return a map like `map[string]int64{"some-storage-class-name": 0}`, this will lead to test failure. We should skip these unchanged numbers.

Secure Kubelet's componentconfig defaults while maintaining CLI compatibility
This updates the Kubelet's componentconfig defaults, while applying the legacy defaults to values from options.NewKubeletConfiguration(). This keeps defaults the same for the command line and improves the security of defaults when you load config from a file.
See: https://github.com/kubernetes/kubernetes/issues/53618
See: https://github.com/kubernetes/kubernetes/pull/53833#discussion_r166669931
Also moves EnableServer to KubeletFlags, per @tallclair's comments on #53833.
We should find way of generating documentation for config file defaults, so that people can easily look up what's different from flags.
```release-note
Action required: Default values differ between the Kubelet's componentconfig (config file) API and the Kubelet's command line. Be sure to review the default values when migrating to using a config file.

Remove unused DeltaFIFO compressor argument to NewDeltaFIFO
Nobody uses it; the one or two older users from 1.4/1.5 timeframe
were removed for 1.6. It's also poorly understood and the sole
example is in the testcases, and it's pretty incomplete.
If anyone really wants compression, they can revert this PR.
Earlier pull was https://github.com/kubernetes/kubernetes/pull/43475 which was blocked on some downstream users, which have now removed their usage of the compressor.

bugfix(mount): lstat with abs path of parent instead of '/..'
**What this PR does / why we need it**:
If a nfs volume with improper permission is mounted on a Pod, operation of deleting this Pod will fail and the pod itself will be stuck at a 'TERMINATING' status. Kubelet cannot reconcile it correctly.
This is because kubelet will try to find the mount-point with '..' file which needs `x` permission of dir. When it's forbidden, the nfs volume will never umount without a correct mount-point finded.

juju: Fix broken ingress after upgrade-charm
**What this PR does / why we need it**:
This fixes a bug that prevents the ingress controller from being deployed after doing an `upgrade-charm`.
Essentially, `worker.auth.bootstrapped` gets cleared during `upgrade-charm`, and it never gets set again. This prevents the `start_worker` and `render_and_launch_ingress` handlers from running, among other things.
This PR fixes that.
