Add option --experimental_discard_actions_after_execution in order to turn it off after a release.
Discarding actions hasn't been shown to have a significant positive effect on heap memory usage, after careful research by mschaller@. It's holding back other projects (threading Fileset metadata through) and adding complexity, so it's time to kill it. Out of an abundance of caution, I'll keep actions in memory via a flag flip, then, if it sticks, I'll change the default, and then I'll unwire everything.
