Display advanced settings of a process

Refs https://redmine.teklia.com/issues/5713 & https://redmine.teklia.com/issues/7136

When a process has started, the advanced settings are stored (gpu, worker activity, farm, ...) and available through RetrieveProcess but never displayed (initially we did not store them so could not retrieve them later on).

We can now easily display all these advanced settings on the process configuration details, simply setting the correct values in the already disabled advanced setting form.
