Description

The current code does hash(pool + seed) which makes pgs from adjacent pools overlap and share the same osds. This is definitely not ideal.

Add a pg_pool_t flag and feature bit and all that to do something different here. Soon, so that we can get support out early and upstream into to kernel etc.
