Add option elasticsearch capture body urls

[jackshirazi]

What does this PR do?

Per the spec this adds the elasticsearch_capture_body_urls option

Note that I've changed the category of the Mongo documentation from MongoDB to Datastore (which is also used for this ES option) following a team discussion that decided this was a better category. That means the existing MongoDB URL will no longer work and anything linking to it will get a 404. I decided this is better rather than making the MongoDB category a redirect page as it was a very niche option and we don't need the extra clutter for such a niche option
