keycloak/keycloak-quickstarts

AI Summary: The task is to improve the Keycloak Kubernetes deployment configuration (keycloak.yaml) by adding a default `initialDelaySeconds` value to the startup, readiness, and liveness probes. This is to address an issue where Keycloak restarts repeatedly in Kubernetes due to slow startup times, especially when using many custom SPIs. The solution involves modifying the existing YAML configuration to include a delay before the probes begin checking the Keycloak instance's health.
