Bug Description

In Sahara we can configure data locality [0]. But this feature is not available for HDP plugin. So we need to add ability to set rack awareness for HDP plugin.

Added rack awareness in HDP plugin

    Rack awareness is added in HDP plugin for maintain data locality
    feature of Hadoop.
    Also renamed decomission_helper.py to requests_helper.py

    note: Ambari allows to set up rack info through cluster creation
    blueprint, but it doesn't work for scaling so that is why we manually
    adds rack info for new instances (when scaling) through Ambari API and
    that is why we manually restarts HDFS and MAPREDUCE2 services after
    scaling.
