> Improve the workflow of cluster management.
> There is an option to configure a default [cluster 
> name|https://github.com/apache/beam/blob/master/sdks/python/apache_beam/runners/interactive/interactive_beam.py#L366].
>  The existing user flows are:
>  # Use the default cluster name to create a new cluster if none is in use;
>  # Reuse a created cluster that has the default cluster name;
>  # If the default cluster name is configured to a new value, re-apply 1 and 2.
>  A better solution is to 
>  # Create a new cluster implicitly if there is none or explicitly if the user 
> wants one with specific provisioning;
>  # Always default to using the last created cluster.
>  The reasons are:
>  * Cluster name is meaningless to the user when a cluster is just a medium to 
> run OSS runners (as applications) such as Flink or Spark. The cluster could 
> also be running anywhere (on GCP) such as Dataproc, k8s, or even Dataflow 
> itself.
>  * Clusters should be uniquely identified, thus should always have a distinct 
> name. Clusters are managed (created/reused/deleted) behind the scenes by the 
> notebook runtime when the user doesn’t explicitly do so (the capability to 
> explicitly manage clusters is still available). Reusing the same default 
> cluster name is risky when a cluster is deleted by one notebook runtime while 
> another cluster with the same name is created by a different notebook 
> runtime. 
>  * Provide the capability for the user to explicitly provision a cluster.
> Current implementation provisions each cluster at the location specified by 
> GoogleCloudOptions using 3 worker nodes. There is no explicit API to 
> configure the number or shape of workers.
> We could use the WorkerOptions to allow customers to explicitly provision a 
> cluster and expose an explicit API (with UX in notebook extension) for 
> customers to change the size of a cluster connected with their notebook 
> (until we have an auto scaling solution with Dataproc for Flink).
