ca87060dcc lvol: add option to change clear method for lvol store creation
Default 'unmap' option stays as it was.

'Write_zeroes' comes useful when one wants to make sure
that data presented from lvol bdevs on initial creation presents 0's.

'None' will be used for performance tests,
when whole device is preconditioned before creating lvol store.
Instead of performing preconditioning on each lvol bdev after its creation.

adb39585ef lvol: add option to change default data erase method
Some users require to do write zeroes operation when
erasing data on lvol. Currently the default method is
unmap. This patch adds flag to spdk_rpc_construct_lvol_bdev
call that changes default erase method. This is also a base
implementation for possible future function for erasing
data on lvol bdev.

Since we lock g_lvol_stores_mutex when add lvs to g_lvol_stores, so
logically speaking, we shoud lock g_lvol_stores_mutex whenever access
g_lvol_stores_mutex. Although I can't figure out specific scenario that
will cause contention if we don't lock it.

This patch fixes lvol delete behaviour.
First, we look if there are any dependencies that disallow lvol deletion.
If there are any (i.e. dependent clones) we fail.
Otherwise we delete lvol and unregister associated bdev.

destroy_bdev no longer deletes lvol.

the cluster map memory changing while another thread
is accessing the cluster map.

Therefore, spdk_blob_resize needs to be asynchronous.

8887697f8c bdev/lvol: add UUID to lvols
In addition to the lvolstore uuid, add a per-lvol uuid for bdev
identification.

The lvol uuid is stored as an xattr for each lvol blob; if an lvol blob
without a uuid xattr is encountered, the lvol bdev will not report a
uuid for now (it will be set to all zeroes, which will be treated as
no uuid available by the generic bdev layer).

4ebe8214dd lvol, blob: make channel operations number configurable for blob.
We need to make the channel operations numbers configurable for blob.
Reason: for iSCSI tests, if there is one CPU core, there will be only
one channel, thus read stress tests would
fail since we need more operations for blob channel.

Select a value equal to the small buffer size(8192) for
bdev layer, thus we can solve the iSCSI read issue
correctly. Since for bdev read, we currently only
allow 8192 active bdev I/o requests, so this solution should
work.

PS: Current solution is still not perfect, I think the very
precise fix is that we need to restrict sending I/Os
to the blob, if there is no channel operations. Though
current code, we have retry I/O in bdev , but it still fails
the iSCSI high pressure test.

Using the ** paradigm is a bit problematic for asynchronous

that some error paths would zero the pointer while others
did not.  So make this just a plain pointer, which simplifies
