🐛 ClusterCacheTracker: Stop pod caching when checking workload cluster

[killianmuldoon]

Check if the clusterCacheTracker is running on the workload cluster using an uncached client. Previously Pods were being cached by the controller runtime client which could cause unnecessarily high memory usage.

Really really nice catch and neat fix :) !! This had pretty high impact on environments with a high number of clusters / pods.

(approving directly as the fix is straightforward and I'll use this improvement directly in further scale testing)
