    UT: Run test_plugins as separate process
    
    This commit changes to run test_plugins in a separate process.
    
    test_plugins touches urlpatterns and Site registry during setUp(),
    but the cleanup process in tearDown does not recover urlpatterns correctly.
    After tests under test_plugins run, the urlpatterns continues to have
    entries of test panels and this leads to NoReverseMatch error when
    rendering other panels after that.
    
    I investigated details in setUp/tearDown of PluginTestCase but failed
    to find a good solution to recover urlpatterns and Horizon Site registry.
    As a workaround, runnig test_plugins in a separate process can avoid
    the issue.

Title:
  unittest: NoReverseMatch for test panels sometimes happens

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  NoReverseMatch error occasionally happens in openstack_dashboard unit tests.
  For example, NoReverseMatch: u'plugin_panel' is not a registered namespace inside 'horizon:admin'
  This seems to depends on the order of tests executed.

  Recent examples are:

  Captured example is http://paste.openstack.org/show/739018/

  In addition, horizon current unit test does not catch errors in template rendering.
  This can be enabled by specifying debug=True in OPTIONS parameter in TEMPLATES.
