Summary: Allows disabling the storage of checkpoints related to torchft. Users don't really have to rely on any external storage. So it reduces set up time to get things up and running. Since we also don't really need model checkpoints when we have torchft. And if checkpoint storage has issues, this can work as a killswitch to completely disable the storage so it doesn't impact training. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).
