Allow for multiple controllers reconciling same resource type but with different labels

[goldmann]

Bug Report

I have a use case where it would be great to have trow (or more) controllers being able to reconcile the same resource type.

Let's imaging we have a ConfigMap and controller X and Y. Depending on the "type" of the ConfigMap we would like to have applied different reconciliation workflows.

Having to squeeze it in a single controller would be pretty complicated and unnecessary. Instead we could just mark the ConfigMap with a proper label and the use labelSelector on the @ControllerConfiguration annotation so that the resource is picked up by correct controller.

Currently it doesn't work:

Caused by: io.javaoperatorsdk.operator.OperatorException: Cannot register controller 'generationrequestreconciler': another controller named 'operationgenerationrequestreconciler' is already registered for resource 'configmaps/v1'

As discussed this is a know limitation for now (not really a bug :) ), but will implement it since this is a valid use case.
