The rest looks good

We've made feature gates specific to the leases resource, so I don't think we need to maintain the excludedInternalResources here, we could add it if we need it more in the future

[Iceber]

If there is more demand for skipping resource configurations in the future, then it may be necessary to add a --exclude-resources flag, but I don't think I'd really want to do that, because the people who use clusterpedia and the people who deploy clusterpedia may not be the same, and it's not appropriate to silently skip some resources.

In the future it is still recommended to exclude resources on PediaCluster. #617

This pr allows users who have created a large number of pediaclusters to skip leases without modifying PediaCluster, which is a good value for existing users.
