             Summary: Implement mini cluster for Python
                 Key: KUDU-3470
                 URL: https://issues.apache.org/jira/browse/KUDU-3470
             Project: Kudu
          Issue Type: Task
            Reporter: Marton Greber


The control shell concept has been introduced to simplify/unify the client testing (https://github.com/apache/kudu/commit/761ce10b797c4f6345f0b84cfe30bcc92e346893)
In Java a proper mini cluster has been implemented in MiniKuduCluster.java.
However in Python we only have a bare minimum cluster start/stop functionality, with the option of hard coded default flags. There are many deficiencies for example the inability to set custom flags on a per test case basis, customise/interact with the mini cluster in an easy way.

This came up during testing considerations for JWT support. This is tightly coupled to a proper mini cluster setup, as the mini cluster spins up to oidc. Furthermore the jwt cluster object is necessary to create the jwt: https://github.com/apache/kudu/blob/master/src/kudu/integration-tests/security-itest.cc#L537
During these operations protobuf is used, which is to this point not introduced to the Python testing infra (it uses JSON).
