upgrade step might fail due to old yum caches

[Michele Baldessari]

So before we do a yum update -q -y in the main upgrade step. We need to do a yum clean all before as
well.

I noticed my L->M upgrades failing because the newly added mitaka repos were not picked up
automatically by yum. I overwrote the existing liberty repos with the following steps:

curl -o /etc/yum.repos.d/delorean.repo http://trunk.rdoproject.org/centos7-mitaka/current-passed-ci/delorean.repo
curl -o /etc/yum.repos.d/delorean-deps.repo http://trunk.rdoproject.org/centos7-mitaka/delorean-deps.repo

This could be an issue on all node types. I wonder if we should clean the cache globally as part of major-upgrade-pacemaker-init.yaml step.

I think this makes sense yes. It would reduce the chance of any errors on all nodes
