> Add Robot test to verify Container Balancer for EC containers

> Issue Type: Test

> Priority: Major

> Currently there is a robot test for container balancer for RATIS container.
> We should add robot test for EC case as well.
> Test case:
> 1. Move 1 datanode to maintenance mode (we use 4 datanodes in this test)
> 2. Create multiple keys (after loading the data, we check that 3 datanodes
> are ~60% busy, and the one that is in maintenance mode is empty)
> 4. Start datanode recommission (wait until datanode recommissioning is
> completed)
> 5. Start container balancer (wait until container balancer is completed)
> 6. Check results (after balancing on all 4 datanodes, we should see
> approximately the same data distribution.)
