[SURE-9487] Fleet takes long time to create a bundledeployment (180+ gitrepos)

SURE-9487

Issue description:

At a larger gitrepo scale a applying a new gitrepo using labels takes a long time to create the bundledeployment

Repro steps:

• create a huge number of gitrepos. (k apply -f gitrepos.yaml) gitrepos.yaml is attached to the case
• create one extra git repo that has targets using labels

  paths:
    - /hello-world
  repo: https://github.com/rbreddy/bundledependency.git
  targets:
    - clusterSelector:
        matchLabels:
          foo: bar

• watch the resources :

kubectl get clusters -n fleet-default --output-watch-events --watch-only | ts '%Y-%m-%d %H:%M:%S' | tee  -a output.txt 
kubectl get bundles -n fleet-default --output-watch-events --watch-only | ts '%Y-%m-%d %H:%M:%S' | tee -a output.txt

• Label a cluster to get a gitrepo targeting it:

kubectl label cluster.management.cattle.io <CLUSTER-ID> -n fleet-default foo=bar --overwrite | ts '%Y-%m-%d %H:%M:%S' | tee -a output.txt 

*watch resources on the DS cluster: e.g.

kubectl get pods -n hello --watch | ts '%Y-%m-%d %H:%M:%S' | tee -a output.txt

• Actual behavior:
  fleet takes time to create bundle deployments and start creating resources

• Expected behavior:
  fleet should immediately create bundle deployments and start creating resources

• Additional notes:
  With 300 gitrepos it takes 2 minutes
