31b367ba97 ocf: add callback argument to vbdev_ocf_construct()
Add callback for construct function.
It is not asynchronous yet, but will be after
  adopting asynchronous OCF API

Also adopt RPC construct call for this change.
This is done in this patch because (1) change is small (2) leaving
  implementation as TODO still requires implementing a mock because we
  decided that callback should be required rather than optional.

8d3d32b982 ocf: pass vbdev in callback of mngt_ interface
Add vbdev as another argument in callback of vbdev management operations.
This is nice for async version of vbdev_ocf_construct() which uses mngt_
  interface and creates vbdev structure.

25df73f5d2 ocf: Add management context
Add structure vbdev_ocf_mngt_ctx that is going to be used
  for asynchronous management operations.
Using such context, dynamic memory allocations are no longer required
  (except for one time poller registration)

This patch also adds functions to modify context in a predictable way.
They are very important for complex flow of management operations in OCF bdev
  especially after whole OCF API gets changed to asynchronous.

9977424df1 ocf: make vbdev_ocf_delete function asynchronous
vbdev_ocf_delete function accepts callback now.
RPC delete_ocf_bdev is also updated to adopt this change.

ca1b5c418d ocf: switch to dynamic queues
Use new queue API to manage OCF queues dynamically
This change allows for dynamic creation and deletion of queues
  on get_ and put_ io channel.

Qeueues no longer depend on number of cores in SPDK.

Queue-to-pollers mapping list is removed as well
  as locks "q_ocf_lock" and "vbdev->_lock" as they became redundant

199080cfa2 OCF: rpc: add get_ocf_bdevs method
Add new RPC method for OCF bdev: get_ocf_bdevs
It is useful in respect to not registered OCF bdevs
  which do not appear in standard get_bdevs call

d1fee489a7 OCF: add OCF module
Add OCF module based on OCF meta-library
Open CAS Framwework (OCF) is high performance block storage
  caching meta-library
It is open-source, published at https://github.com/Open-CAS/ocf

With this patch OCF-enabled device is represented in SPDK
  as virtual bdev having core and caching devices as its base devices

This patch includes implementation of:
  * OCF top adapter          (vbdev_ocf.c)
  * OCF bottom adapter       (dobj.c, data.c)
  * Adaptation layer for OCF (env/)
  * OCF context abstractions (ctx.c)

Adaptation layer and context abstractions are not dependent on SPDK bdev

OCF bdev supports reads and writes, configured at startup
Other features will be added with separate patches
