ATM we're supporting two modes:
- XWiki manages the Chrome Docker container (pulls the right Docker image, creates the container, starts, stop and removes it)
- XWiki reuses a local Chrome Docker container
The goal of this issue is to add a third mode:
- XWiki connects to a remote Chrome instance (running inside Docker or not, doesn't matter)
This implies adding a new configuration option to specify the host / IP address of the remote Chrome instance.
