Enable Authorization for HBase

We currently do not support authorizing requests against HBase.

This epic is intended to track the subtasks that we need to accomplish in order to add this functionality.
For the purpose of this epic I think we can ignore authentication, which should be covered under a separate issue.

This needs serious refining, below I have added a few first thoughts around this issue that hopefully can serve as pointers during refinement:

• investigate if we can reuse the Ranger authorizer with OPA (I have some code available for this)
• adapt operator to allow enabling secure mode
• integrate with opa operator
• create opa ruleset to authorize based on data sent by authorizer
• define crds to specify access control lists for hdfs in k8s and cretae functionality for operator to translate this for opa
• much more

Beginne damit, dieses Epic in konkrete Unteraufgaben rund um den HBase-Operator, den sicheren Modus, die OPA-Integration, Autorisierungsregeln und CRDs für die HDFS-Zugriffskontrolle zu verfeinern. Im Issue werden weder Dateien noch Tests genannt, und die Abschlusskriterien sind noch nicht definiert; die Verfeinerung muss die Einstiegspunkte, Akzeptanztests und den Umfang der Autorisierungsunterstützung festlegen.
