[REFAC] - Standardise PluginPreset controller

[IvoGoman]

As part of the standardisation of the reconciliation loop for Greenhouse controllers, this controller needs to be updated to follow the common recommendation for the Reconciliation

Acceptance Criteria

• Implement the Interface
• Use the standardised patch for updating the status instead of the deferred update (if applicable)
• Convert the tests to use test.TestSetup (if applicable) including creation of missing resources
• Remove dedicated finalizers used on the controllers because they are replaced with standard ones.
