Steps to reproduce

We've started moving UI to react/JS and using single page apps for both explore V2 and SQL Lab. Currently we don't have support for translations on the front end, and have yet to come up with a pattern of getting translated strings from the server to the front end.

One first step is to wrap all the strings on the frontend with something like gettext on the python side, as in _('Translate this string'). I heard webpack can help with extracting the strings, then it'd be a matter of feeding that to [python's] babel somehow. An obvious optimization is to only send the translations needed by the user, I'd guess that webpack can create an entry file for each language.

Unfortunately it's not super high priority for us though, so we probably won't drive this and act more as enablers.

As I know, superset can translate the words in .html and .py file easily, but the words in .js or .jsx can't be translated. I found a solution in http://www.obviel.org/en/1.0b/i18n.html, and I try it locally, it works. but everytime I merge the newest code from your repository, it takes lots of time. Could you please add this found to your code?

Let me link this on how sentry (python + react frontend) does this:

We have done this, and in superset/superset/assets/javascripts/explore/stores added some resource files, the realization of the page of Chinese.Such as the following page.

@lxzhangchao then open a PR to contribute the work back or i don't see what we are discussing here :)
