    SAMZA-1417: Clear and recreate intermediate and metadata streams for batch processing

    For each run of a batch application, we need to clear the internal streams from the previous
run and recreate new ones. This patch introduces the following:
    1) isBatch flag to StreamSpec
    2) app.mode (BATCH/STREAM) in the application config
    3) app.runId and use it to generate the internal topics for each run. generation is not addressed in this pr. There will be another patch to resolve
it for both yarn and standalone. For now, this patch only works for yarn.
