Buildstream local cache doesn't get cleanup automatically when the disk is full

Summary

If the disk gets fill up, build will fail and the only solution is to rm -r the buildstream cache folder

What is the expected correct behavior?

If the disk is full, buildstream should automatically cleanup, similar to what what happen when you set a quota

Possible fixes

A possible solution would be (when we fix #733 (closed)) to change the defaults from

quota: infinity

to

quota: 100%

• BuildStream version affected: 1.2.3
