Upgrade failure when service parameter is changed for PankoApi

Upgrade failure when service parameter is changed for PankoApi

scenario001 env in ocata has mapped PankoApi locally and it
has been removed master scenario001 env file. In tripleo.sh
upgrade command, both old (ocata) and new (master) env files
are included, because of which new service file is not used,
as it has been removed. This change is to add the PankoApi
mapping back to scenario001 env file for now. Actual fix
will be remove old env file from upgrade command of tripleo.sh.
