Revert PR #418 "Merge branch eni-cleanup into master"

[yash97]

This reverts commit b5a054e.

With this PR CNInode latency creation is gone.

Proof:-

1. Created two images one with current master branch and another with this PR.
2. Provisioned extra 50 nodes in cluster and watched creation of nodes and cninodes every 10 seconds.
3. Results with master branch which has latency:

                                   Tue Sep 17 04:46:10 UTC 2024
	                            having nodes
					50
					having cninode
					12
					Tue Sep 17 04:48:39 UTC 2024
					having nodes
					50
					having cninode
					47


					Tue Sep 17 04:48:50 UTC 2024
					having nodes
					50
					having cninode
					50

As you can see it took nearly two minutes for cninodes to get created after nodes are created.

4. Result with Image of this branch:

                           Tue Sep 17 05:21:49 UTC 2024
					having nodes
					8
					having cninode
					8
				Tue Sep 17 05:22:12 UTC 2024
					having nodes
					49
					having cninode
					49


				Tue Sep 17 05:22:23 UTC 2024
					having nodes
					50
					having cninode
					50

As you can see here node creation and cni node creation is toe to toe with almost negligible difference.

If we are cutting the next release from release-1.4 branch, do we want to revert this PR from master branch?
Just TOL if it might be easier to sync the release-1.4 branch with internal repo and cherry-pick the commits.
