Move Keycloak provider prerequisites out of crossplane-init

What does this MR do and why?

closes #4198 (closed)

crossplane-init was waiting for Keycloak-related secrets, although these resources are not required by crossplane itself. They are prerequisites for the Crossplane Keycloak provider, so they should be owned by a Keycloak-provider-specific init unit.

This MR moves the Keycloak-specific external secret out of crossplane-init into a new dedicated crossplane-provider-keycloak-init unit and moves the related secret health checks to this new unit.

Global config for deployment pipelines

• autorun pipelines

• allow failure on pipelines

• record sylvactl events

Notes:

• Enabling autorun will make deployment pipelines to be run automatically without human interaction
• Disabling allow failure will make deployment pipelines mandatory for pipeline success.
• if both autorun and allow failure are disabled, deployment pipelines will need manual triggering but will be blocking the pipeline

Be aware: after configuration change, pipeline is not triggered automatically. Please run it manually (by clicking the run pipeline button in Pipelines tab) or push new code.
