For the CHAP setting of iSCSI targets, JSON-RPC handles the
value of parameters directly and dump of iSCSI targets can be
used to construct directly.
For the CHAP setting of iSCSI discovery session, the same manner
will be applied.

A net implementation should be allowed to not create a socket group.
It would basically mean that it is not participating in polling at all.
This came up during VPP integration. To enable using both types of sockets,
all types are polled within socket group. There is possibility of VPP
not being initalized at all (VPP process not running or failing connecting).
This would result in hard requirement of VPP always running when its
support is compiled into SPDK. Handling NULL here allows VPP to opt-out of
this polling.

Portal, portal group, initiator group, and target node don't use fixed size
array anymore. To use the same naming rule in iSCSI subsystem and in SPDK
is helpful to understand and maintain. Current naming rule is not bad but
to use unified and compact name is prioritized at this time.
This patch changes function names as follows:
- spdk_iscsi_init_tgt_nodes() -> spdk_iscsi_parse_tgt_nodes()
- spdk_cf_add_iscsi_tgt_node() -> spdk_iscsi_parse_tgt_node()
- spdk_iscsi_portal_grp_array_create() -> spdk_iscsi_parse_portal_grps()
- spdk_iscsi_portal_grp_create_from_configfile() -> spdk_iscsi_parse_portal_grp()
- spdk_iscsi_portal_create_from_configline() -> spdk_iscsi_parse_portal()
- spdk_iscsi_portal_grp_array_destroy() -> spdk_iscsi_portal_grps_destroy()
- spdk_iscsi_init_grp_array_create() -> spdk_iscsi_parse_init_grps()
- spdk_iscsi_init_grp_create_from_configfile() -> spdk_iscsi_parse_init_grp()
- spdk_iscsi_init_grp_array_destroy() -> spdk_iscsi_init_grps_destroy()
For example "parse" is already used to explain the operation in portal_grp.c.
Hence using "parse" is familiar and not strange in iSCSI.

This patch is to add the basic support of QoS on bdev.
Including two major functionalities:
1. The QoS rate limiting algorithm:
a. New IO will be always queued first also under
the no memory condition
b. Start the QoS IO operation based on the limit
c. A poller started in each millisecond to reset
the rate limit and send new IOs down
d. The rate limit is based on the millisecond and
converted from user configurable IOsPerSecond
2. The Master Thread management:
a. Add a per bdev channel_count
b. Whenever QoS is enabled on bdev, if QoS bdev
channel is not created, create the QoS bdev
channel and assign the QoS thread
c. When new IOs coming from different channels
(threads), pass the IOs to the QoS bdev channel
through the thread event
d. When the IOs are completed from the QoS bdev
channel, pass the IOs back to its orignal
channel(thread)
e. Destroy the QoS bdev channel when it is the
last bdev channel for this bdev. Defer the
destruction if current thread is not QoS thread

This patch extracts iSCSI subsystem initialization by .INI config file
into a function spdk_iscsi_parse_iscsi_globals().
Naming rule was adopted from NVMf-tgt.
By these two patches,
iSCSI subsystem init is done in spdk_iscsi_parse_iscsi_globals().
iscsi subsystem config is done in spdk_iscsi_parse_iscsi_configuration().
The purpose of the patch series is
- to separate iSCSI subsystem initialization and iSCSI subsystem
configuration, and
- to develop a new JSON-RPC by reusing the separated iSCSI subsystem

Currently only thin_provisioned zeroes back_bs_dev is supported.
There was no unit tests for channel in this bs_dev, because it's never used.
However, unit tests in patch https://review.gerrithub.io/c/393935/ show that channel is wrong.
This patch passed proper spdk_io_channel to callback function.

Briefly tested with SPDK target via bdevio
through both vhost-user and QEMU's virtio-pci.
vhost-blk driver is not mentioned in any doc yet.
A virtio-blk bdev can be created as following:
`construct_virtio_user_blk_bdev /tmp/virtio.0 MyVirtioBlk0 --vq-count 16`
`construct_virtio_pci_blk_bdev 0000:01:00.0 MyVirtioBlk1`
or
```
[VirtioUser0]
Path /tmp/vhost.0
Type Blk
Queues 16
[VirtioPci]
Enable Yes
```
If `Type` field is not present, the VirtioUser
section will be parsed as a SCSI one, preserving
backward compatibility.

There was a bug reported by Cunyin Chang with regards to how the
cmb_current_offset was calculated when the CMB offset into the CMB BAR
is non-zero. This patch fixes this issue and also fixes the problem
that the last valid offset into the BAR *may* differ if registration
is utilized or not (due to the 2MiB alignment and length requirements
for registered memory).

Since we have two pollers for each iSCSI polling group,
so it could be possible that the nop_poller to set
iSCSI connection in existed or existing state.
So add a check here, which means the incoming data
is too late.

blobfs and lvol can now use this to automatically iterate
all existing blobs during spdk_bs_load. Changes to blobfs
and lvol will come in future patches.
This will also be used in some upcoming patches which need
to iterate through blobs during load to determine
snapshot/clone relationships.
