    being populated.

  - Insert vcpe customer service workflow into SO catalogdb

    Customer service workflow entry will be automatically
    inserted into catalogdb database if running with
    oom_mode set to True.

    So database endpoint properties were updated to
    reflect current catalogdb location.

    vCPE doc updated to reflect the changes made.
