Config Setting for Parameter Names

[mattbloomfield]

Could we get config settings for changing the URL parameter names, similar to what we have with tokenParam and the various triggers?

Specifically, the x-craft-preview parameter causes problems because once a bot knows you are running Craft it can bypass your cache and hammer on your backend till your site goes down. The only good way of blocking it is to block that parameter in your edge layer or web server, which effectively disabled preview links.

This makes us and many others quite sad.
