Add Cloud Run v1 Multi-Container Example with New Fields (GoogleCloud…

…Platform#7971)

* cloudrun: Add container name field for Services

Adds the template.spec.containers.name field for specifying container
names in Cloud Run v1 Services.

* cloudrun: Update the description of the Service containers field

Updates the description of the Cloud Run v1 Service field
template.spec.containers to reflect that the field is repeated and to
remove other obsolete information.

* cloudrun: Add empty dir volume type for Services

Adds the beta template.spec.volumes.empty_dir field for configuring
ephemeral volumes in Cloud Run v1 Services.

* cloudrun: Add multi-container Service example

Adds an example google_cloud_run_service resource with multiple
containers and a shared empty dir volume. Container dependencies are
specified as a json encoded annotation.
