Fix Owner References Issue

Prior to this fix, the GarbageCollector in kube-controller-manager was not deleting the deployer job after the application was deleted. This error started occurring on k8s 1.20+

Increase deletion timeout

Use the same timeout as the installation.

0.10.12

Allow selection of storage class provisioner in mpdev:

Introducing optional property storage_class_provisioner

Usage:
mpdev verify --deployer="$DEPLOYER" --wait_timeout="$WAIT_TIMEOUT" --image_pull_secret="$IMAGE_PULL_SECRET" --storage_class_provisioner=kubernetes.io/vsphere-volume

Supported values:
kubernetes.io/vsphere-volume
kubernetes.io/gce-pd

If no value is provided, kubernetes.io/gce-pd is used by default

Require specific cluster-scoped permissions

Improve user security and transparency by requiring cluster-scoped permissions to be specific (vs. cluster-admin).

Update kubectl versions in deployer image

Updates kubectl versions and removes older versions to decrease image size

Cleanup dangling APIServices

• Cleanup unavailable APIServices
• Allow consuming scripts/verify parameters from GCS

Fix schema validation warning

Fix load_schema_and_validate() (#528)

* Fix load_schema_and_validate()

* Update validation warning end marker

Add assistedClusterCreation

Releases the x-google-marketplace.assistedClusterCreation schema feature.

Publicize custom deployer permissions

• Adds documentation for the deployerServiceAccount property
• Validates that deployerServiceAccount permissions are appropriate

Add description to SERVICE_ACCOUNT property and improve test hermeticy

Add a description to the SERVICE_ACCOUNT property to enable explaining important permissions to the user.

Make mpdev verify tests more hermetic by setting the namespace as the owner of cluster-scoped resources so that they are deleted after the test (not performed in mpdev install).
