    [SPARK-21958][ML] Word2VecModel save: transform data in the cluster

    ## What changes were proposed in this pull request?
    Change a data transformation while saving a Word2VecModel to happen with distributed data
instead of local driver data.
    ## How was this patch tested?
    Unit tests for the ML sub-component still passes.
    Running this patch against v2.2.0 in a fully distributed production cluster allows a 4.0G
model to save and load correctly, where it would not do so without the patch.
