Add manual ovs upgrade script for workaround ovs upgrade issue

When we upgrade OVS from 2.5 to 2.6, the postrun package update
restart the services and drop the connectivity
We need to push this manual upgrade script and executed to the
nodes for newton to ocata

The special case is needed for 2.5.0-14 specifically see related
bug for more info (or, older where the postun tries restart).
See related review at [1] for the minor update/manual upgrade.

issues:
- During the ovs upgrade for 2.5 to 2.6 we need to workaround the classic
yum update command by handling the upgrade of the package separately to not
loose the IPs and the connectivity on the nodes. The workaround is
discussed here https://bugs.launchpad.net/tripleo/+bug/1669714
upgrade:
- The upgrade from openvswitch 2.5 to 2.6 is handled gracefully and there should
be no user impact in particular no restart of the openvswitch service. For more
information please see the related bug above which also links the relevant code reviews.
The workaround (transparent to the user/doesn't require any input) is to download the OVS
package and install with --nopostun and --notriggerun options provided by the rpm binary.
