Fix bug 1373264
	Coming up with supervisor-support-service supervisor group to manage the support services like rabbitmq-server
	only rabbitmq-server is added in it, later can add required services like keepalived, haproxy etc.

	Fix upgrade, In 1.10, setup.sh was packaged in contrail-setup and contrail-install-packages
        So when upgrading contrail-install-packages, it will fail, we will need to use rpm -iU --force to upgrade
        To avoid this and use yum localinstall, post section for using setup.sh.new is done.
