Feature request - change forcastle root path

[rodrigo14miguel]

Feature
Ability to change forecastle app root path

Use case
Serve several instances of forecastle under the same FQDN but through different paths.

Current issue
I have tried doing URL path rewrite through ingress controller, something like exposing one forecastle instance through example.com/firstinstace. When opening this URL in the browser, it tries some GETs of assets and favicon though the apps root URL example.com/ which leads to a broken page.
If the apps root could be changed, there would be no need to do a path rewrite.

How to
I don't understand react but I found this article https://skryvets.com/blog/2018/09/20/an-elegant-solution-of-deploying-react-app-into-a-subdirectory/ that explains the issue and how to solve it in the an-instruction-for-the-solution-with-base-url-element section.
