Don't run yum_update.sh inside docker
For now, don't run anything in yum_update.sh when it is run from inside the heat-agents container. A mechanism for doing a yum update on the host can be worked out later, but for now a yum update should never be run inside a container. Change-Id: I73d37578f8b2dc9c3029b968b1ef74ef4894100a
