3a58b2fb2f bdev/ocssd: append command
This patch adds support for the append operation.  The user doesn't need
to specify the exact location of where the data should be placed, but
only need to pass starting LBA of a zone to append to.  The user can
retrieve the address the data was written at during completion callback.

1ad438311e bdev/ocssd: request resubmission
If a spdk_bdev_io cannot be completed, because it is sent to a zone that
is currently busy, reschedule its submission.  This mechanism will be
used by appends, as mutliple append commands can be directed to the same
zone at the same time.

ffd53b6bad bdev/ocssd: update write pointers
Update write pointers during successful write / reset completion.  This
is needed in order to support the append operation.

This patch also introduces the zone busy flag, which makes sure only one
write (or reset) operation can be active at a time.  If a request is
directed to a zone that is already processing another operation, it will
be completed with a failed status.

b63be39461 bdev/ocssd: move bdev_ocssd_get_zone_by_slba
Move bdev_ocssd_get_zone_by_slba up in the file.  This function is going
to be used by many others, so it makes sense to be defined near the top.

88406f3302 bdev/ocssd: retrieve chunks' info during initialization
OCSSD bdev needs to keep track of some portion of zone's state (write
pointer, its capacity, whether it's busy) in order to support the append
operation.  To achieve that, all the info needs to be retrieved for all
of the chunks and translated to zone format.

6e640cfcbf bdev/ocssd: wrap IO part of bdev_ocssd_io
Wrap the part of the bdev_ocssd_io responsible for describing IO
operations in a separate structure.  Currently all fields are wrapped
this way, but it'll allow the bdev_ocssd_io to become a union of several
different types of structures (one for the IO operations, one for
getting zone information, etc.).

6bda87b324 bdev/ocssd: create / delete calls
Added a way to create and delete OCSSD bdevs on top of OC NVMe
controller.  The controller can be created using the regular NVMe bdev
RPC call.  For instance, the following (assuming 0000:00:04.0 is an
OC device):

 rpc.py bdev_nvme_attach_controller -b nvme0 -a 0000:00:04.0 -t pcie
 rpc.py bdev_ocssd_create -c nvme0 -b nvme0n1

creates Open Channel controller nvme0 and OCSSD bdev nvme0n1 on top of
it.  The bdevs can be deleted either by the bdev_ocssd_delete call or by
deleting whole NVMe controller, in which case all bdevs are destroyed.

a116324c88 bdev/ocssd: initial Open Channel bdev implementation
This patch adds initial Open Channel zoned bdev implementation.  The
bdev will allow to use the zoned API on top of OCSSD devices.

Added the ability to create the OCSSD NVMe controller.  The controller
is created using the regular NVMe's RPC when the controller is detected
to be Open Channel.
