Remove need to setup job and environment

[zblz]

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://[email protected]/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.
