Ever growing collection of stack and ssh directories in /tmp

[rodcloutier]

Problem description

Each run of the reconciliation loop for a stack creates two directories in /tmp. When in exponential back-off each error will produce the directories quickly filling the disk if the program is large.

The /tmp directory does not seem to be clean-up afterward.

@viveklak I believe this was fixed with #111?

[viveklak]

Yes it was - closing.

This is still an issue for me as of v0.0.19. Primarily go-build and pulumi_auto directories. It fills up then the pod is evicted. Seems like they never get cleaned. Should this issue be reopened? @viveklak

@jsravn Looks like this can indeed happen if the workspace fails to be initialized (e.g. you have the wrong token or config etc.) But these are the situations which are retried aggressively. I have reopened and will address.

[viveklak]

There is still a problem with a work directories under repos. The current cleanup only cleans the workdir and leaks the rest of the repo. The ideal fix is #78. But we should make every effort to cleanup any additional files generated.

[liamawhite]

We end up having to use volumes anyway (I think due to our use of a monorepo). The volume fills up over time as pods are killed mid-reconcile. Obviously, we can fix this by increasing the graceful shutdown period, but it would be better if on startup the operator looks for old auto_workdirs and cleans them up.
