Properties option to remove utm_product_name param from the Sourcegraph URL

[prat0318]

I installed Sourcegraph Intellij plugin and it works great for our on-premise Sourcegraph instance. One thing i noticed is that the url adds the below params to the url making it bigger and clumsier to share with others:

&editor=JetBrains&version=v1.2.0&utm_product_name=IntelliJ+IDEA&utm_product_version=2020.1

It will be great if we can have a .properties option to remove these optional params.

Happy to come up with a PR as well for this.
