explore possibility of native integration auth better without cross-site cookies.

This would be great to have so that customers can try out code host integrations during trials, when their Sourcegraph instance may not have TLS set up yet. See https://sourcegraph.slack.com/archives/CMT39K56Z/p1586799834129200?thread_ts=1586798352.127800&cid=CMT39K56Z:

This is a big downer for trials. Setting up TLS is a long process typically at big companies

@uwedeportivo it looks like this never got moved out of 3.15. Were you already working on this / planning to work on it soon? If not, I think the web team should own this.
