0.12.0

Summary

This release introduces a "validating admission webhook" (https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#validatingadmissionwebhook) for beiboot objects. Requested Beiboot clusters are checked for an active or terminating namespace and are rejected in such cases. This is currently tested with EKS and GKE (both not private cluster versions). The Kubernetes configs for running the Beiboot operator have been extended for this functionality.
The beiboot-config object serialization has been improved, so strings are no longer double-double quoted. Please remove this ConfigMap before installing the new operator version.
The Beiboot client now checks if requested port-forwardings are actually free on the local machine before establishing the connection.
