Since stats builder is implemented for retrieving cache, core and ioclass stats,
adapters should use it instead.

13cf871a13 Per-execution-context freelists 
Global free cacheline list is divided into a set of freelists, one
per execution context. When attempting to map addres to cache, first
the freelist for current execution context is considered (fast path).
If current execution context freelist is empty (fast path failure),
mapping function attempts to get freelist from other execution context
list (slow path).

The purpose of this change is improve concurrency in freelist access.
It is part of fine granularity metadata lock implementation.

d10c618065 Move parts metadata to separate section 
Fix problem introduced by increasing partition name size to 1024 bytes,
which effectively made superblock bigger than one page. Due to this
flushing superblock required more than one io, which in case of dirty
shutdown between these ios resulted in CRC missmatch and made cache
recovery impossible.

Moving parts metadata to separate sections makes superblock fitting
in one page, effectively solving described problem.

global concurrency lock, which won't be needed after per-bucket
