nova upgrade failing through kolla-ansible

[Satya Sanjibani Routray]

While upgrading nova from the code base 05/12/2016 to the code base 20/12/2016
the nova upgrade fails with error ""msg": "Container exited with non-zero return code""

tried upgrading from code base 29/11/2016 to 05/12/2016 which works fine

seems like nova introduced the cell_v2 as a fix of "https://bugs.launchpad.net/tripleo/+bug/1649341"
which broke the upgrade
