Adding changes to handle updation of yum Management cache in rhel.

[kmadnani]

This issue is happening with Ansible 2.4.0.0+ wherein the playbook hangs for hours while updating yum management cache and ultimately fails.

This is happening only with RHEL, in CENTOS it works fine.

I would like to see an upstream bug in Ansible about this yum check-update issue, but let's land this as it is.
