metal3: Add Metal3Cluster and Metal3ClusterTemplate views

[mastermaxx03]

Summary

Continues the Metal3 plugin. Adds Metal3Cluster and Metal3ClusterTemplate to the Metal3 section, the CAPM3 resources for the cluster side of a Cluster API cluster on bare metal. More resources and a map view to follow.

Included

• Metal3Cluster list and detail views with provisioned state, control plane endpoint, and cluster columns.
• Metal3ClusterTemplate list and detail views with the cloud provider setting.
• The Metal3 sidebar group extended with the two new entries.

How to test

• A cluster with the Metal3 and CAPM3 CRDs installed.
• cd metal3 && npm install && npm start, then run Headlamp.
• Apply the sample: kubectl apply -f metal3/test-files/metal3cluster.yaml.
• Open the Metal3 section: the clusters and templates list, and clicking one opens the detail view.
