While unloading cas_cache module, volume types were deinitialized, although core
pool still wasn't empty. Now this deinitialization can be done after removing
cores from core pool, and before context is freed.

This needs to be done in caller application context. As part of asynchronous
management API rework, volume_open callback was moved to kernel worker thread
context. To work around this, atomic parameters are now read before cache
attach/load/probe and provided to bottom volume via volume params.
