When upgrading from 11 to 12, python-pankoclient isn't installed

[Nagasai Vinaykumar Kapalavai]

Description of problem:
Deployed 11 without the additional panko template. Upgraded it to 12. Tested telemetry. The unified cli commansds about events aren't working: "openstack metric event list" and such, but "ceilometer event-list" is working, although ceilometer is supposed to be deprecated. Turns out that python-pankocilent wasn't installed.

Version-Release number of selected component (if applicable):
openstack-panko-common-3.0.0-4.el7ost.noarch
openstack-panko-api-3.0.0-4.el7ost.noarch
python-panko-3.0.0-4.el7ost.noarch
puppet-panko-11.3.1-0.20171101200600.da8c9b1.el7ost.noarch

How reproducible:
100%

Steps to Reproduce:
1. Install RHOS11 without enable_telemetry = true for undercloud and without additional panko template
2. Upgrade to 12
3. In overcloud try to get openstack metric event list

Actual results:
Get an error that the command is not in the list of openstack commands

Expected results:
The list of events
