Optimize Repeated registration of AlgorithmProvider when ApplyFeatureGates
**What this PR does / why we need it**:
modified ApplyFeatureGates() just add/del features, cancel the register of all AlgorithmProvider.
there is Repeated registration of all AlgorithmProvider when ApplyFeatureGates() runs;
AlgorithmProvider have already registered when package defaults loaded;
I think ApplyFeatureGates() is just add/del features, it needn't register all AlgorithmProvider again

Highlight nodeSelector when checking nodeSelector for Pod.
**What this PR does / why we need it**:
Currently, we are using function name as `PodSelectorMatches` to check if `nodeSelector` matches for a Pod, it is better update the function name a bit to reflect it is checking `nodeSelector` for a Pod.
The proposal is rename `PodSelectorMatches` as `PodMatchNodeSelector`.

Don't require failureDomains in PodAffinityChecker
`failureDomains` are only used for `PreferredDuringScheduling` pod
anti-affinity, which is ignored by `PodAffinityChecker`.
This unnecessary requirement was making it hard to move
`PodAffinityChecker` to `GeneralPredicates` because that would require
passing `--failure-domains` to both `kubelet` and `kube-controller-manager`.
