Remove need to setup job and environment

It would be great if `faculty-distributed` handled all platform requirements. A way to achieve this could be to create a Job when `FacultyJobExecutor.map` is called. The command of the job could also install `faculty_distributed` to avoid the need for a server environment: `pip install -U git+ssh://git@github.com/facultyai/faculty-distributed.git && faculty_distributed_job $path $worker_id` with the appropriate parameters. Resource requests and optional additional server environment IDs could be passed as constructor arguments.

Optionally, the job could deleted as part of the cleanup function.
