Michael Ionkin 9f8c2197c0 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.
