The other important point (mentioned in the issue but I think it's
important to outline it here) concerning the analyzers is that they are now
defined per index: there are no global analyzers, you have to define them
for every index using the analyzer. It is totally different from our
current approach and make defining them manually (and maintaining them)
even more cumbersome. Thus I don't think we can consider defining them
manually as an option.

If we want to support Es 5, we need to provide a way to define these
analyzers in HS and make HS post them to Es.
