add readOnly use case to raw block device proposal
This PR is an addendum to the #1265 to dictate the behavior of the container runtime for read-only devices as specified in the PVCVolumeSource. The precedence already exists for filesystems thus having a consistent behavior for the user. UC9 was added to illustrate the usage.

removed deprecated munge script instructions
There is no `hack/update-munge-docs.sh` script. Documentation should not refer to it.

Remove Disk Allocatable Evictions
After https://github.com/kubernetes/kubernetes/issues/52336, which uncovered a bug in disk accounting, I have struggled to see why ephemeral-storage allocatable evictions are necessary.
For CPU and Memory allocatable, enforcing allocatable through cgroups provides protection from being starved of compute resources by user pods.
However, for ephemeral-storage it seems that the node-level enforcement mechanisms are able to prevent the node from running out of disk, and thus prevent impact to system daemons.
Additionally, memory usage metrics read from cgroups or statfs are far more reliable than an aggregation of `du` calls which may be collected at different times (as https://github.com/kubernetes/kubernetes/issues/52336 demonstrated).
(As a side note, we should read from the /kubepods cgroup to determine allocatable memory usage)
We should still keep the scheduling aspects of node allocatable for ephemeral storage, as this allows for proper accounting. But I would like to remove enforcement of node allocatable for ephemeral storage.

Add a design doc for admission webhook bootstrapping
Originally distributed as a [google doc](https://docs.google.com/document/d/1pw6FyobY3pVxfWYwmAFuF5WJpvjfq-M3Ciz996kblVc/edit?ts=59f1d824#).
The idea is from an Oct. 23 meeting with lavalamp, cheftako, deads2k, smarterclayton, liggitt. It also draws inspiration from #1191.

Add sig labels and use aliases in OWNERS files
This PR does the following:
- Creates a sig-*-leads alias for all sigs and working groups
- Replaces the reviewers/approvers in the sig folders and design-proposals folders with that alias
- Adds a label field to the OWNERS files to allow for automatic sig labelling (https://github.com/kubernetes/test-infra/pull/3502)

Proposal: SubResources for CustomResources
[CustomResourceDefinitions](https://github.com/kubernetes/community/pull/524) (CRDs) were introduced in 1.7. The objects defined by CRDs are called CustomResources (CRs). Currently, we do not provide subresources for CRs.
However, it is one of the [most requested features](https://github.com/kubernetes/kubernetes/issues/38113) and this proposal seeks to add `/status` and `/scale` subresources for CustomResources.
