Non-voting gate of tempest tests on new arch

[Tim Hinrichs]

We should have a non-voting gate job that runs the tempest tests on the new architecture.
This will require using scripts/start_process.py instead of congress/harness.py, setting the config option 'distributed_architecture' to True, and running the tempest tests. Highly recommend making that work manually before worrying about the gate.

    Launch Congress with distributed_architecture flag is true

    Check codes for distributed_arch flag is written on global scope in
    each file. The flag is loaded at python module loading time. The file
    doesn't use a value specified in congress.conf since initialization
    steps of config values are done after loading config file.

    This patch enables Congress to use distributed_architecture flag
    with True in the devstack tests and in local tests.
