Story (Required)

When the resources are cached in Argo CD, there is no filtering mechanism and all resources irrespective of whether it is managed by argo cd or not, and occupies memory in cache. By having a filtering informer, we can have a resource filtering function that can filter out only those resources that are managed by Argo CD and store that in the cache. This should reduce the amount of memory used by Argo CD for the resource cache.
