krad d9cfaa2b16 Persistent Read Cache (6) Persistent cache tier implentation - File layout 
Summary:
Persistent cache tier is the tier abstraction that can work for any block
device based device mounted on a file system. The design/implementation can
handle any generic block device.

Any generic block support is achieved by generalizing the access patten as
{io-size, q-depth, direct-io/buffered}.

We have specifically tested and adapted the IO path for NVM and SSD.

Persistent cache tier consists of there parts :

1) File layout

Provides the implementation for handling IO path for reading and writing data
(key/value pair).

2) Meta-data
Provides the implementation for handling the index for persistent read cache.

3) Implementation
It binds (1) and (2) and flushed out the PersistentCacheTier interface

This patch provides implementation for (1)(2). Follow up patch will provide (3)
and tests.

Test Plan: Compile and run check
