kubectl: Move utility functions to util package
**What this PR does / why we need it**:
`parseFileSource()` and `parseLiteralSource()` are utility functions.
We have a package already for utility functions, `kubectl/util/`.
Move utility functions to `kubectl/util`, capitalize function names to
export from package.

Fix spam of multiattach errors in event logs
We should be careful while generating multiattach errors.
We seem to be generating too many of them because old code

Remove containers from deleted pods once containers have exited
Issue #51899
Since container deletion is currently done through periodic garbage collection every 30 seconds, it takes a long time for pods to be deleted, and causes the kubelet to send all delete pod requests at the same time, which has performance issues. This PR makes the kubelet actively remove containers of deleted pods rather than wait for them to be removed in periodic garbage collection.

**Note**: This is not hooked up to anything. A release note will be added when this is wired into actual commands.
Major changes:
- Don't generate a patch, instead generate the merged object so it can be used with PUT
- Separate tree parsing logic to collate items in a list from the delete / merge / replace / add logic when merging
- Use openapi for merge strategy metadata so it works with extensions and version skew
- Support multi-field mergekeys when merging lists
- Support replace strategy for maps
- Reduce complexity of generating order when merging lists - keep the locally defined order and append remote only-items
Continue to support:
- Explicitly setting fields to null
- Merging lists of primitives
- Don't randomize ordering when merging lists

fix broken cloud provider info urls
kubernetes/community repo's commit 3034683c5997474d9f59ef722c8ee9c1f1e58f07
started a re-org of the design-proposals directory to have hierarchical
structure and subdirectories. This in turn broke the urls in the
kubernetes/kubernetes/pkg/cloud-provider/README.md file. This patch adds
the appropriate subdirectories into the urls in the readme.

RBAC objects are now stored in etcd in v1 format. After completing an upgrade to 1.9, RBAC objects (Roles, RoleBindings, ClusterRoles, ClusterRoleBindings) should be migrated to ensure all persisted objects are written in `v1` format, prior to `v1alpha1` support being removed in a future release.

Implement CRI stats in Docker Shim
**What this PR does / why we need it**:
This PR implements CRI Stats in the Docker Shim. It is needed to enable CRI stats for Docker and ongoing /stats/summary API changes in moving to use CRI.
Related issues:
#46984 (CRI: instruct kubelet to (optionally) consume container stats from CRI)
#45614 (CRI: add methods for container stats)
This PR is also a followup to my original PR (https://github.com/kubernetes/kubernetes/pull/50396) to implement Windows Container Stats. The plan is that Windows Stats will use a hybrid model: pod and container level stats will come from CRI (via dockershim) and that node level stats will come from a "winstats" package that exports cadvisor like datastructures using windows specific perf counters from the node. I will update that PR to only export node level stats.
