    libide/foundry: add API to setup run context for pipeline
    
    The goal here is to setup the run context similarly to when we are running
    applications, but in the format that we'd expect for build pipelines. This
    can be used by shellcmd to run "differently based on locality".
    
    We still need the runtime plumbing to differentiate though.
