Refactor some codes, add filter objects, and add support for lable filtering...

[Forget-C]

refactor&feat&fix&style:
1. Unify parameter types and divide them into two categories: normal parameters kor.Opts and filter parameters filters.Options.
2. includeExcludeLists no longer participates in cmd args binding, and is taken over by filters.Options.
3. The initialization operations of includeNamespace and excludeNamespace are taken over by filters.Options and will only be executed once.
4. Add filters.Framework object to uniformly process filtering logic.
5. All currently supported resources are supported by the kor/used=true tag.
6. Fix the problem that filterOptions.Validate does not take effect
7. Support includeable parameters

The unit tests have passed, but due to the large scope of the changes, more tests are needed.

[Forget-C]

The original purpose was to abstract the filter framework to facilitate the addition of filter parameters. Other changes are necessary to achieve this goal. #187
now, If we want to add a filter, we only need the following steps：

create filter func

// FilterFunc is a filter that is a function
// If the resource is legal, return true
// example:
// deployment.Spec.Replicas > 0; return true
// meta.GetLabels()["kor/used"] == "true"; return true
type FilterFunc func(object runtime.Object, opts *Options) bool
func TestFilter(object runtime.Object, opts *Options) bool {
	if meta, ok := object.(metav1.Object); ok {
		if meta.GetLabels()["kor/used"] == "true" {
			return true
		}
	}
	return false
}

Set a name

const  TestFilterName = "test"

Add to registry

func NewDefaultRegistry() Registry {
	return Registry{
		LabelFilterName:    LabelFilter,
		AgeFilterName:      AgeFilter,
		KorLabelFilterName: KorLabelFilter,
                TestFilterName: TestFilter,
	}
}
