Runs a local WSGI server bound on a free port and having the Placement
application with NoAuth middleware.
Optionally, the caller can choose to not use a wsgi-intercept and use
this fixture to set up configuration and (optionally) the database.
It's possible to ask for a specific token when running the fixtures so
all calls would be passing this token.
This fixture takes care of starting a fixture for an in-RAM placement
database, unless the db kwarg is False.
Used by other services, including nova, for functional tests.
