Incrementing to Catalog-To-Xpublish v0.1.2 (and other minor changes)

Changes:

• Incremented catalog_to_xpublish to v0.1.2 which includes a bug fix for the fault assert logic in run_server.py causing failure to build. All tests pass in this builder and catalog_to_xpublish repos.
• Minor improvement/cleanup in the performance testing code because I couldn't overlook the obvious issue.
• The USE_OVERRIDE switch in compose.yml was erroneously left on true! I switched it back to false.

I ran the (fixed) docker-compose locally and the server was built! That said, credential errors (perhaps expected) are thrown when trying to access data endpoints.
