Replace hand-written informers with generated ones
Replace existing uses of hand-written informers with generated ones.
Follow-up commits will switch the use of one-off informers to shared
informers.
This is a precursor to #40097. That PR will switch one-off informers to shared informers for the majority of the code base (but not quite all of it...).
NOTE: this does create a second set of shared informers in the kube-controller-manager. This will be resolved back down to a single factory once #40097 is reviewed and merged.
There are a couple of places where I expanded the # of caches we wait for in the calls to `WaitForCacheSync` - please pay attention to those. I also added in a commented-out wait in the attach/detach controller. If @kubernetes/sig-storage-pr-reviews is ok with enabling the waiting, I'll do it (I'll just need to tweak an integration test slightly).

Decrease Daemonset burst replicas due to DoS conditions.
**What this PR does / why we need it**:
We are seeing DoS conditions on our Registry if were running a large cluster with too many daemonsets bursting at once.
**Special notes for your reviewer**:
I decided not to plumb through yet another variable to the command line. Ideally such parameters could be tweaked via a configuration file.
**Release note**:
```release-note
NONE
```
secifically we need to differentiate between wanting to run,
should run and should continue running. This is required to
support all taint effects and will improve reporting and end
user debuggability.
Add dsStoreSynced so we also wait on this cache when starting the
DaemonSetController.
Switch to using a fake clientset in the unit tests.
Fix TestNumberReadyStatus so it doesn't expect the cache to be mutated.

daemonset: bail out after we enqueue once
This isn't terrible because we dedup in the queue but it's a waste of
cycles.
Restoring the code which was removed in 528bf7a. When there are no sufficient
resources on node or there is a conflicting host port event is emited.
It helps with debugging.
Fixes#31369
In order to determine whether a node should run its daemon pod,
DaemonController creates a dummy pod based on DaemonSet's template and
then uses scheduler predicates (currently GeneralPredicates) to test
whether such pod can be run by the node. The problem was that
DaemonController was not setting Namespace for the dummy pod. This was
not affecting currently used GeneralPredicates but this problem could
bite later when some namespace-dependent predicates are added to
GeneralPredicates or directly to DaemonController's node checks
(e.g. pod affinity).
Stumbled upon it while working on e2e test for #31136
