Noticed that some dependencies were being downgraded as part of the change - reverted such changes.

This linter warning is confusing:

 internal/pkg/daemon/apparmorprofile/apparmorprofile.go:29:2: Expected 'a', Found 'c' at internal/pkg/daemon/apparmorprofile/apparmorprofile.go[line 29,col 2] (gci)
	ctrl "sigs.k8s.io/controller-runtime" 

but it pretty much means that the imports must be sorted alphabetically. I think the linter has a --fix option that should do all that.

[jhrozek]

the code looks OK to me btw

[pjbgf]

@jhrozek thank you for the review and pointing out the linter issue. PTAL
