Fix neutron-fwaas cover tests

[James Arendt]

The tox.ini command for 'tox -e cover' breaks with error:
cover runtests: commands[0] | python setup.py testr --coverage --coverage-package-name=neutron_fwaas --testr-args=
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]

Appears to be same issue as found in neutron-vpnaas and fixed there under https://review.openstack.org/#/c/217847/

    Fix neutron-fwaas cover tests

    The tox.ini command for 'tox -e cover' breaks with error:
    error: option --coverage-package-name not recognized

    Appears to be same issue as found in neutron-vpnaas and fixed
    there under https://review.openstack.org/#/c/217847/

    Applying same fix to neutron-fwaas.

    Same logic applies to 'tox -e cover-constraints', though
    because upstream changed 'upper-constraints.txt' eventlet
    to 0.18.3 in middle had to set to local stack value to run:
    export UPPER_CONSTRAINTS_FILE=/opt/stack/requirements/
    upper-constraints.txt

    Closes-Bug: #1546793
    Change-Id: I82fde90d1ed17f2495f8560b8e56febc10e3013c
