refactor: drop cosi controller install

[takirala]

What problem does this PR solve?:

Depends on https://github.com/mesosphere/konvoy2/pull/3474 and https://github.com/mesosphere/konvoy2/pull/3521

Once konvoy is cosi ready with/without caren, we can revert the cosi controller deployment in kubecost. This will affect kind cluster CI (as it would be missing cosi controller) so we need to fix it in kommander repo before merging this change.

Which issue(s) does this PR fix?:

https://jira.nutanix.com/browse/NCN-105279
