Brian Waldon 112fc71ba4 Instantiate wsgi app for each worker
A single WSGI app, and therefore a single sqlalchemy engine (mysql
connection), was being used across all API workers. This patch
instantiates the WSGI app once per worker rather than up front to
give a separate database connection to each worker.

Fixes bug 1036193
