Investigate RemoteSettings requests params and try to reduce info leaked about local state
From https://trac.torproject.org/projects/tor/ticket/31740#comment:7:
One concern is that the different parameters (etag, timestamps...) might be leaking enough info about the user state that it allows linking together requests done over time as belonging to the same user. In principle, the request parameters depend on the values returned in previous responses, and these seem not to change very often. I did not do a deep analysis, but I feel like we would not lose too much by doing the same requests without parameters (as if there was no previous state in the browser). I don't see the responses being so big, nor the requests done so often.
