Description of the problem:

After successfully deploy Orchestrator Operator and having it deploy rhdh, if the rhdh name or project name are changed in the orchestrator cr, a new project or backstage instance is created, but the original instance is not cleaned up.

How reproducible:

100%

Steps to reproduce:

1. Deploy Orchestrator operator M5 and have Orchestrator deploy RHDH
   Orchestrator CR rhdh example:

  rhdh:
    devMode: false
    installOperator: true
    name: rhdh
    namespace: rhdh 

1. Edit orchestrator CR and change the name or namespace to a difference value

Actual results:

A new backstage and/or namespace are created, but the original is not removed.

Expected results:

Seems more logical the original would be removed.
