to verify the shared airflow installation will work for search
platforms needs.

Adds one bit outside of the dedicated search_platform directories, to
facilitate passing the REBUILD_FIXTURES env var through tox and past
the fixture that overrides environment vars. This supports the
existing search-platform test methodology of fully rendering a task
and recording how it will be run in production to files. This method
has helped in the past to recognize what all is being changed when
shared functionality is changed, along with giving an easy place to
lookup the complete invocation to understand what exactly airflow is
going to invoke under the hood when running a task in spark. The
