8f58add152 Lru populate unsafe 
The unsafe mode is useful if the metadata of added cores is incomplete.

Such scenario is possible when starting cache to standby mode from partially
vaild metadata.

fc7c901c8b Skip collision init on cache start passive 
Recovery during passive start is based on the assuption that metadata collision
section stored on disk might be partially valid. Reseting this data would make
rebuilding metadata impossible.

48bc6c2f6b Always use async queue kick in management pipeline 
Management pipelines tend to consist of multiple asynchronous steps.
Allowing synchronous queue kick results in massive call stacks (e.g.
almost 500 functions deep in case of cache stop). Since async kick
is required anyway, it seems reasonable to switch to async kick
in pipeline implementation.
