PO file: translator notice is ignored

[Akihiro Motoki]

After Horizon team decided to use pybabel to extract message catalogs,
"Comments for Translators" [1] are ignored.
PyBabel does not support "Comments for Translators".
Is there any solution?

I see several strings in our test codes are marked as translatable and they have no translation comments.
I tried to add comments for translators, but I failed to do it.

Pybabel migration almost succeeds but it is one of drawbacks.
We are now not compatible with Django standard way.

To raise an attraction, I intentionally target it to Mitaka-RC1.
Feel free to move it out.

After investigating this, it turns out that we need to pass "--add-comments=Translators: " to pybabel extract.
At now the infra script does this, so horizon is not directly related.
One thing to be fixed is run_tests.sh --makemessasges.
Thus we can mark it as Low and there is no need to target it to Mitaka-RC1.

Some fix is needed in Horizon side too.
Hopefully it is merged before Mitaka release.

    Honor comments for translators when extracting messages

    To extract commments for translators, '--add-comments' option
    must be passed to pybabel. Comments for translators were extracted
    when we used Django tools to extract messages, but when we switched
    to pybabel it was lost. This commit adds the option to run_tests.sh.

    Move the place of existing comments for translators
    so that pybabel can find them. Django tool and pybabel
    expect a bit different places.
    Also add comments to ungettext_lazy in test codes.
