Fixes bad heuristic when calling "tc show" to check interface
`tc` sometimes returns stuff that has more than 12 words in its response. The heuristic is bad, but this at least fixes the case when `tc` is returning too much.
Fixes#28571.

Add checks in Create and Update Cgroup methods
This PR is connected to upstream issue for adding pod level cgroups in Kubernetes: #27204
Libcontainer currently doesen't support updates to parent devices cgroups. Until we get libcontainer to support skipping devices cgroup we will have that logic on the kubelet side.
This PR includes:
1. Skip the devices cgroup when updating a cgroup. We only update the memory and cpu subsytems.
2. We explicitly pass all the cgroup paths that don't already exist to Apply()
3. Adds an AlreadyExists() method which is a utility function to check if all the subsystems of a cgroup already exist.
On cgroupManager.Update() we only call Set() and cgroupManager.Create() we only call Apply() method

@derekwaynecarr I'm still experimenting to make sure this satisfies the need downstream, but looking for agreement in principle

Move KUBE_GIT_UPSTREAM out of init.sh and into *-munge-docs.sh.
It is only used in those 2 scripts and this way we can set the value dynamically.

Some scheduler optimizations
Ref #28590
This PR doesn't do anything fancy - it is just reducing amount of memory allocations in scheduler, which in turn significantly speeds up scheduler.

Prep for not checking in generated, part 2/2
This PR is extracted from #25978 and build on #28578 - it is just the conversion related parts. All the Makefile stuff is excluded.
@wojtek-t this is literally branched, a bunch of commits deleted, and a very small number of manual fixups applied. If you think this is easier to review (and if it passes CI) you can feel free to go over it again. I will follow this with a conversion-related PR to build on this.
Or if you prefer, just close this and let the mega-PR ride.
@lavalamp
This fixes PodSpec to generate cleanly. No other types only half-generate (so
now we Fatalf), though several fail to generate at all (only Errorf for now).
There are ample opportunities to optimize and streamline here. For example,
there's no reason to have a function to convert IntStr to IntStr. Removing the
function does generate the right assignment, but it is unclear whether the
registered function is needed or not. I opted to leave it alone for now.
Another example is Convert_Slice_byte_To_Slice_byte, which just seems silly.
This drives conversion generation from file tags like:
// +conversion-gen=k8s.io/my/internal/version
.. rather than hardcoded lists of packages.
The only net change in generated code can be explained as correct. Previously
it didn't know that conversion was available.
This is used subsequently to simplify the conversion generation, so each
package can declare what peer-packages it uses, and have those imported
dynamically, rather than having one mega list of packages to import and not
really being clear why, for any given list item.
