Failure to delete a namespace causes the controller to hang about projects-operator HOT 3 CLOSED

Hey @djoyahoy!

Yea we've encountered this a few times, usually when there's a failure to clean up a resource in the namespace. Since this is default behaviour for a terminating namespace, I'm not sure we can do much to alleviate the problem. But from your issue, are you suggesting to make the error message clearer? If so, that would seem reasonable enough to me

HI @gmrodgers. I think a clear error message in the logs makes sense. Thanks!

A potentially preferable solution is to set MaxConcurrentReconciles to something above 1. This can be done using https://github.com/kubernetes-sigs/controller-runtime/blob/bac7e8aaf90acf319cf58f7441e3847096c7bd52/pkg/builder/controller.go#L143 when initialising the manage, which we currently do here: https://github.com/pivotal/projects-operator/blob/b70879416de1f91dff9c5805da84cc528c112c6a/controllers/project_controller.go#L95
