Release v0.28.0

[gianlucam76]

🚀 Features:

• management cluster is automatically registered to be managed by Sveltos;
• sveltosctl register command has been expanded to specify labels SveltosCluster should have;
• sveltosctl generate kubeconfig has been introduced. Running this command while pointing to the managed cluster, will generate and output a Kubeconfig that can be later on consumed by sveltosctl register cluster
• sveltosctl register command accepts a new flag fleet-cluster-context that can be set to the context pointing to the managed cluster. So this command can be run with default context pointing to the management cluster and it will automatically generate a kubeconfig and register the cluster in one shot.

🐛Bug fixed:

• add-on controller will correctly redeploy an helm chart when its values are modified (read more about bug here)
