[SPARK-10699] [ML] Support checkpointInterval can be disabled
Currently use can set ```checkpointInterval``` to specify how often should the cache be check-pointed. But we also need the function that users can disable it. This PR supports that users can disable checkpoint if user setting ```checkpointInterval = -1```.
We also add documents for GBT ```cacheNodeIds``` to make users can understand more clearly about checkpoint.
