Add more process attributes to the entity #2655

Progresses #2655

Changes

This adds more process attributes to the process entity to provide additional context and utilise information known at start up. As exit code is not known at start up it doesn't make sense to have them on the resource.

Note: if the PR is touching an area that is not listed in the existing areas, or the area does not have sufficient domain experts coverage, the PR might be tagged as experts needed and move slowly until experts are identified.
