fix: Improved resiliency of removal logic

[AlexanderSehr]

Description

• Updated removal order as image templates must be removed before e.g., permissions are revoked
• Updated 'alreadyProcessed' logic to not accidently exclude resources that contain a name as a substring, aber are an actual sub-resource
• Updated logic to fetch deployment operations as the previous logic did also include 'existing' resources in specific situations. It's now using REST and filters those out (i.e., 'read' Operations)
• Enabled the removal logic to deal with cases where no resources are deployed (e.g., later utl modules)
• The logic now differentiates in between 'I can not find a deployment' and 'I can find a deployment, but it has no resources linked' (before it was only the former)
• Finally, the logic was slightly altered to not give up as soon as no deployment is found, but instead try and find as many as possible and only throw an exception after the removal logic ran end to end.
