[cisco-voip] UCM Upgrade Poll

[Lelio Fulgenzi]

To add to this, we had a unity connection v11.5 install go awry because it didn't make sure the serviceability component was completed installing before timing out and restarting the server. The TAC had never seen anything like it before. No errors in the install logs. Just an entire missing component. 

Adding because I know how close the cucm and connection installs are.

We then make sure we can replicate two or three successful upgrades. That takes anywhere from a week to two weeks if we're able to concentrate on just those tasks. But that's never the case.
