Add data-processing service for Sahara
Add data-processing service for Sahara

When registering endpoint with data_processing keystone transforms it
into data-processing. This problem causes sahara to not find the
endpoint afterwards

We need to have two endpoints for correct working tempest and horizon
with devstack. After resolving bug in tempest and horizon need to remove
old data_processing endpoint
