vmware unit tests broken

[Salvatore Orlando]

commit 79c97120de9cff4d0992b5d41ff4bbf05e890f89 introduced a constraint which causes a vmware unit test to fail.
This unit test indeed directly exercises the plugin - creating a context with get_admin_context. For such context, tenant_id is None, and the DB constraint on the default security group table fails.

    vmware unit tests: tenant_id must be in neutron ctx

    Fix a unit test which previousluy passed a context without
    a tenant identifier to the plugin. This triggered a database
    constraint failure in the default security group table.

    Restore and fix vmware unit tests

    This patch actually restores vmware unit tests, by adding back
    the __init__.py file which was renamed during the advanced
    service spinoff and not reinstated when fixing vmware code to
    comply with the spinoff.

    Furthermore, this patch also fixes a minor issue with context
    usage in vmware unit tests which is triggering failures because
    of the new database constraint introduced with the commit
    79c97120de9cff4d0992b5d41ff4bbf05e890f89

    Finally, flake8 tests on vmware directories are also restored
    with this patch.
