Improve `es_info` method output readability

In my case, es_info method output readability is not optimal:

• tabulation breaks if screen width is too small (screenshot below), a possibility might be return an object declaring a _repr_html_ method to have nice display in notebook environment
• since es_info is probably only useful in interactive environment, it might be relevant to directly print output instead of returning a string

@sethmlarson I prefer as well a solution that avoids cutoffs, even if it means a longer output. An additional improvement could be a html table in notebooks by implementing _repr_html_ method: it would avoid cutoff by providing horizontal scroll + would keep a compact output.

Would it makes sense in your opinion to “split” es_info in multiple methods? For instance es_mappings, es_operations etc ?

@NickolayVasilishin Agreed! Having an object is definitely preferred.
