Release v0.57.1

[gianlucam76]

🚀 Features

1. Support for CEL Rules

Introduced CEL (Common Expression Language) rule support across multiple resource types. These rules enhance dynamic evaluation and validation capabilities, and can now be defined for the following instances:

• Classifier
• EventSource
• HealthCheck
• SveltosCluster liveness and readiness checks
• Techsupport

2. Configurable Token Duration for Token Renewal

Added an optional tokenDuration field to the TokenRequestRenewalOption struct, allowing fine-grained control over token validity:

If tokenDuration is set, it defines how long the token remains valid.
If not set, the system falls back to renewTokenRequestInterval.
This ensures tokens can be renewed proactively, reducing risk during brief network outages.

3. Event Generation on Feature Deployment

The system now emits events when features are successfully deployed to a cluster via ClusterSummary. These events provide visibility into the deployment process and include details about the feature and target cluster.

4. EventTrigger destinationCluster Field

Introduced a new field, destinationCluster, in the EventTrigger resource. This field, a corev1.ObjectReference, can be expressed as a template. It addresses scenarios where an event in one cluster (e.g., a management cluster) necessitates deploying resources to a different, specific cluster.

If defined, Sveltos will first instantiate destinationCluster (using both Resource and source cluster data), then set the ClusterProfile.Spec.ClusterRefs.
