> "checkpointInterval" is member of DecisionTreeParams in Scala API which is inconsistency
with Python API, we should unified them.
> * checkpointInterval
> ** member of DecisionTreeParams <-> Scala API
> ** shared param used for all ML Transformer/Estimator <-> Python API
> Proposal:
>  "checkpointInterval" also used at ALS but the meaning for that is different from here.
> So we make "checkpointInterval" member of DecisionTreeParams for Python API, it only
validate when cacheNodeIds is true and the checkpoint directory is set in the SparkContext.
