distbuild: Add example cluster for deployment

Since the nodes are deployed as NFS root file systems, there's no
VERSION_LABEL field in this cluster, as there is no upgrade method.
The build nodes are stateless and deployed fresh each time.

+name: example-distbuild-cluster
+kind: cluster
+description: |
+  This is an example cluster morph that can be adapted to set up a
+  Baserock distributed build network.
+
+  You will need to deploy a Trove for the distributed build network
+  to use before deploying this cluster. The worker SSH key file should
+  be generated as part of the Trove deployment. It is the key used by
+  workers to authenticate with the Trove to give them read access to
+  all source repositories.
