Switch processors implementation in v2alpha1 reconciliation

[barchw]

Description
Api-gateway reconciliation loop will support separate loops for both v1beta1 and v2alpha1 after #1016. The follow up to this switch is to make sure that reconciliation processors used in the v2alpha1 loop will operate on the v2alpha1 APIRule version.

Reasons

• The v2alpha1 reconciliation loop is using v1beta1 processors.
• Support for new functionalities, like ext-auth handler, should use v2alpha1 APIRule as base for how to reconcile.

TODO:

•  Create issue for unifying test builders: Unify test resource builders #1224

PRs:

• v2alpha1 AuthorizationPolicy processor #1211
• V2alpha1 RequestAuthentication processor #1228

DoD:

• Provide unit and integration tests.
  - [ ] Provide documentation.
  - [ ] Verify if the solution works for both open-source Kyma and SAP BTP, Kyma runtime.
  - [ ] If you changed the resource limits, explain why it was needed.
• Verify that your contributions don't decrease code coverage. If they do, explain why this is the case.
  - [ ] Add release notes.
