Description

This is a followup to https://github.com/apache/arrow/pull/1445

Right now, objects allocated on GPUs are never evicted. There should be a flag with the maximum amount of memory that plasma can take on the GPU. If this memory is exceeded, objects should be evicted according to the policy (which is pluggable).
