Define marquez.yml for API load test

[wslulciuc]

Problem

PR #2047 updated the DB host in marquez.dev.yml needed for api-load-test.sh. The update in the config file was a breaking change as discussed in PR 2355

Solution

This PR generates a marquez.yml file used by api-load-test.sh to run the API load test. This PR also reverts the DB host update in marquez.dev.yml.

Note: All database schema changes require discussion. Please link the issue for context.
