@parikshithb you can rebase on #1839 to make ci pass instead of waiting until it is merged.

Looks good, see suggestion for new comment.

Can you share the log before/after this change?

Can you share the log before/after this change?

1. Before there was no logs for create/annotate namespace.
   After adding debug logs for create/annotate namespace:

2025-02-18T22:48:56.732+0530	DEBUG	util/namespace.go:38	Created namespace "e2e-subscr-deploy-rbd-busybox"
2025-02-18T22:48:56.788+0530	DEBUG	util/namespace.go:124	Annotated namespace "e2e-subscr-deploy-rbd-busybox" with "volsync.backube/privileged-movers: true"
2025-02-18T22:48:56.801+0530	DEBUG	util/namespace.go:35	Namespace "e2e-subscr-deploy-rbd-busybox" already exist
2025-02-18T22:48:56.801+0530	DEBUG	util/namespace.go:38	Created namespace "e2e-subscr-deploy-rbd-busybox"
2025-02-18T22:48:56.819+0530	DEBUG	util/namespace.go:124	Annotated namespace "e2e-subscr-deploy-rbd-busybox" with "volsync.backube/privileged-movers: true"

2. Moved from info to debug for deleteNamespace:

2025-02-18T22:56:02.197+0530	DEBUG	disapp-deploy-rbd-busybox	util/namespace.go:61	Waiting until namespace "e2e-disapp-deploy-rbd-busybox" is deleted
2025-02-18T22:56:10.277+0530	DEBUG	disapp-deploy-rbd-busybox	util/namespace.go:72	Namespace "e2e-disapp-deploy-rbd-busybox" deleted

Failed again, this time during appset relocate:

Will rebase and push.

Accessing github from the e2e lab is very flaky now, and not related to change.
