Change default region for placement to empty string

As per tempest design, if tempest conf is not having any region for
a service then identity region should be used. In case of placement
the default value is "RegionOne" which is considered as placement
region if region missing in tempest conf. In order to have identity
region to be used as default we need to change to empty string for
placement service. Empty string can be seen being used in other
services like volume, image etc.

Please check the below link for the logic of default region
