HTML output generation may break horizon plugin unittests

[Akihiro Motoki]

After merging a patch which generates HTML output report for unit tests [1], trove-dashboard unit test starts to fail.
Most horizon plugins import openstack_dashboard.test.settings and they do not have nosehtmloutput in their test-requirements.txt necessarily.

openstack_dashboard.test.settings should consider this case.

The check for htmloutput module availability looks required.

    HTML test report only when nosehtmloutput is installed

    Most horizon plugins import openstack_dashboard.test.settings
    in their test settings, but they do not necessarily have nosehtmloutput
    in test-reqs. Assuming nosehtmloutput potentially breaks plugins tests,
    we check the availability of htmloutput module (from nosehtmloutput)
    and specify --with-html-output option if available.
