[lance5890]

1. Extract the release image from ocp-release:4.20.0-ec.3, found that there are a few unused yaml in the 4.20 version, as follows:

2. we have to analysis every exact yaml to decide which should be reserved and which should be removed
3. As the cvo reconcile all these yamls in the directory, and too many unused yamls will cost memory consumption, remove these yamls will to do some help to speed ​​up the reconcile too in the 'permute-flatten-by-number-and-component' model
