Explore using $TMPDIR

[ericfranz]

If the render is file io heavy, copying the project to TMPDIR and rendering the scene files there would make sense. Of course if rendering one scene in a job, we might consider avoiding copying rendered files from other scenes to TMPDIR (i.e. copy everything but images dir and scenes dir, then select scene and image files to copy).

Also, if we did this we would want to be copying the resulting exr frames from the TMPDIR back to the home directory as they were created because walltime is very likely to kill the job.

Why is this still needed:

frame-renderer/jobs/video_jobs/maya_submit.sh.erb

Lines 12 to 13 in f69b5ac

	# set a new tmpdir bc that's what the container needs to look at
	export TMPDIR="/tmp"

It's not apparently? TMPDIR is still set to /tmp/$JOD_ID in the container, but maya (or whatever library that gives the tmpfile) must be able to error then just use /tmp directly.
