Remove topology configmap on kuadrant operator uninstall

[eguzki]

Link the lifecycle of the kuadrant operator with the topology configmap. Currently, when the operator starts, it will create and maintain the topology configmap in the namespace where the operator is deployed. It is missing the implementation of the removal of the topology configmap when the operator is deleted.

Note: The ConsolePlugin resource, together with the associated deployment and service, follows the life events of the topology configmap. When the topology is created, so it is the ConsolePlugin (on openshift). Whereas when the topology is deleted, so it is the ConsolePlugin and associated resources. The ConsolePlugin was introduced in #884

Is this essential for v1?

I would say it is not.
