openshift_checks: allow OVS 2.7 on OCP 3.5 and 3.6

rpm_version: Allow package_list items to specify a list value for version.
If a list value is provided for a package, pass the check if any version in
that list is found.

ovs_version: Specify both 2.6 and 2.7 as allowed versions of OVS for
OpenShift versions 3.5 and 3.6.
