Timeout and Max-in-flight don't report non-resource URLs correctly.
Unify error reporting for 429 and 504 to be correct for timeout and max in flight and eviction. Add better messages to eviction (removing a todo). Return the correct body content for timeouts (reason and code should be correct).
This potentially increases cardinality of 429, but because non-api urls may be under the max-inflight budget we need to report them somewhere (if something breaks and starts fetching API versions endlessly).
```release-note
The 504 timeout error was returning a JSON error body that indicated it was a 500. The body contents now correctly report a 500 error.

Add support for `no_new_privs` via AllowPrivilegeEscalation
**What this PR does / why we need it**:
Implements kubernetes/community#639
Fixes#38417
Adds `AllowPrivilegeEscalation` and `DefaultAllowPrivilegeEscalation` to `PodSecurityPolicy`.
Adds `AllowPrivilegeEscalation` to container `SecurityContext`.
Adds the proposed behavior to `kuberuntime`, `dockershim`, and `rkt`. Adds a bunch of unit tests to ensure the desired default behavior and that when `DefaultAllowPrivilegeEscalation` is explicitly set.
Tests pass locally with docker and rkt runtimes. There are also a few integration tests with a `setuid` binary for sanity.
**Release note**:
```release-note
Adds AllowPrivilegeEscalation to control whether a process can gain more privileges than it's parent process
```

Unify genclient tags and add more fine control on verbs generated
This will change the syntax of the existing `genclient` tags be like this:
```
// +genclient
// +genclient:noStatus
// +genclient:noVerbs
// +genclient:nonNamespaced
// +genclient:readonly
```
The first one indicates the client will be generated from the struct below and the other tags are basically options to the genclient (which justify why they should be prefixed with `genclient:`)
This also changes the `// +genclientstatus=false` to `// +genclient:noStatus` to follow the pattern and also changes the `// +noMethods=true` to `// +genclient:noVerbs` as we call the REST operations verbs so it will make it consistent with terminology.
In addition to existing options this patch also add two more to allow more fine-grained control on which verbs are going to be generated. This is extra useful for third-party projects (like OpenShift) where some resources does not implement full CRUD, but for example just "create" verb or "create" and "delete"...
To support that, you can use this syntax:
```
// +genclient:onlyVerbs=create,delete
// +genclient:skipVerbs=patch
```
The first one will generate only create and delete functions and second one will generate full CRUD without "patch" actions. This somehow overlaps with the existing "readonly" tag, but I want to keep that tag in place as it reads better in some cases ;-)
