Add RWO_PVC_SCHEDULING env var to the Tensorboard Controller deployment (kubeflow/kubeflow#5266) 

* Add RWO_PVC_SCHEDULING env var to Tensorboard controller deployment

The value of the 'RWO_PVC_SCHEDULING' env var is set to "false" by
default. The user will be able to change the value of the env var
manually by modifying the 'config/manager/manager.yaml' file.

* Update README.md
