Various small enhancements to packaging

**Describe the problem/challenge you have**

- [x] package install wont reconcile changes to app (eg spec.canceled/spec.paused) so that app can actually get deleted
- [ ] package install immediately is considered as ReconcileFailed when it previously failed, and change was made to package install. when change to the app kicks in, package install will flip to Reconciling and ReconcileSucceeded if app succeeds. (this makes kapp deploy fail waiting for PackageInstalls that were already in failing state, even if change is actually going to fix it)
- [x] [investigate] repo deploy is for some reason taking a bit of time (https://gist.github.com/cppforlife/39505210bfdf6f3cb69a7de2671b9ae3#file-slow-yml-L92-L117) -- this is related to default kube-api-burst/kube-api-qps configured for PackageRepo deployment
