Description

Currently, the plasma server exists with a fatal check if not enough memory is available. This can lead to errors that are hard to diagnose, see

https://github.com/ray-project/ray/issues/3670

Instead, we should keep the store alive in these circumstances, taking up some of the remaining memory and allow the client to check if enough memory has been allocating.
