User defined labels for GCP Resources(TP)

This epic covers the work to apply user defined labels GCP resources created for openshift cluster available as tech preview.

The user should be able to define GCP labels to be applied on the resources created during cluster creation by the installer and other operators which manages the specific resources. The user will be able to define the required tags/labels in the install-config.yaml while preparing with the user inputs for cluster creation, which will then be made available in the status sub-resource of Infrastructure custom resource which cannot be edited but will be available for user reference and will be used by the in-cluster operators for labeling when the resources are created.

Updating/deleting of labels added during cluster creation or adding new labels as Day-2 operation is out of scope of this epic.

List any affected packages or components.

• Cluster Infrastructure
