Feature Request

Add revisionHistoryLimit configuration to KeycloakX StatefulSet

Description

Currently, the KeycloakX StatefulSet doesn't expose the revisionHistoryLimit field, which means it uses Kubernetes' default value. It would be useful to make this configurable.

Proposed Solution

Add revisionHistoryLimit to the StatefulSet spec with a default value of 10 (Kubernetes default).

Benefits

• Allows users to control how many old ReplicaSets are retained
• Helps manage cluster resources by limiting history retention
• Follows Kubernetes best practices for StatefulSet configuration
