Allow configuring cleanup of temporary files

[mx-psi]

I am trying to setup codspeed on a multi-module Go repository. On a ubuntu-latest Github runner and I am running into 'no space left on device' errors (full logs).

failed to write raw results: write /tmp/profile.6zEGSoeXO7.out/raw_results/649cad625b718acc06eb36b981d8502f.json: no space left on device
cat: write error: No space left on device

This is intentional, see

codspeed-go/go-runner/src/builder/templater.rs

Lines 38 to 44 in 0b914bf

	// We don't want to spend time cleanup any temporary files since the code is only
	// run on CI servers which clean up themselves.
	// However, when running tests we don't want to fill the disk with temporary files, which
	// can cause the tests to fail due to lack of disk space.
	if cfg!(not(test)) {
	target_dir.disable_cleanup(true);
	}

but unfortunately this is not workable if you need to codspeed run hundreds of times because you have a monorepo (e.g. another repository that I want to use Codspeed on would have to run codspeed run 230+ times). ubuntu-latest seems to have 14GB storage so codspeed seems to be a bit excessive in the amount of temp files it keeps around.

A Linux workaround is to just do rm -rf /tmp/* || true but this tries to delete all temp files, including non-codspeed ones (e.g. systemd ones), and so it would be nice if codspeed-go had this option and it could be passed down by the codspeed runner.

Thanks for the issue, this is indeed a problem that we noted, we will take it on asap.

I think the link to the logs with No space left on device is another error, but I found it.

It does not seem like the rm -rf /tmp/* || true was sufficient for addressing this problem, I am still running out of space. Nonetheless I think this would be a step in the right direction.
