Merge #1984

1984: Support boolean for the no-analytics flag r=Kerollmops a=Kerollmops

This PR fixes an issue with the `no-analytics` flag that was ignoring the value passed to it, therefore a `no-analytics false` was just understood as a `no-analytics` and was effectively disabling the analytics instead of enabling them. I found [a closed issue about this exact behavior on the structopt repository](https://github.com/TeXitoi/structopt/issues/468) and applied it here.

I don't think we should update the documentation as it must have worked like this from the start of this project. I tested it on my machine and it is working great now. Thank you `@nicolasvienot` for this issue report.

Fixes #1983.
