Measure number of facets request to discuss reintroducing features

[alexgarel]

We disabled most of the facets on product opener because it was hammering the server badly because of search bots.

Now that we display a no-index for bots, we could see how many real facets requests we have in logs and see if we can re-enable this feature (BTW we could also try to add it for bots, even on legit facet requests).

We should gather statistics from the server log to measure that (either on facets-knowledge-panel side or on product opener side).

@raphael0202 is there a way to discriminate the "no-index" pages in the access_log (is there a specific message) ?

Sorry, I missed your message! not really for now, we return HTTP 200.
