Capture some graphql query parameters for analytics

[mcannon068nw]

Basic pageviews have already been implemented via #466 but detailed analytics for graphql queries are not currently captured. While how much of the parameter set we should capture is undecided, we should at least capture gene and drug query terms to support grant development.

A method for how we might accomplish this has been generously provided by @acoffman : https://gist.github.com/acoffman/f40c92d8995d6598d479c23d125ff754

To add to this, we should see if perhaps we could find a way to capture ambiguous gene term selections. The idea being if a user uses the ambiguous genes tab, which gene do they select as their intended choice.

This would probably be helpful data for Anastasia to help untangle alias collisions

Per meeting, this will be addressed when we have available developer time
