feat: add requests and limits to registry containers (#1158)

**What problem does this PR solve?**:
Set requests and limits for the registry containers. The addon can be
enabled in every cluster so we want to have control over the resources.
These numbers were collected by pushing a 12GB bundle to the registry.
