Modify the vbdev_get_lvol_store_by_uuid() API function to take the UUID
as a string instead of a uuid_t, since this simplifies the calling code.
This also allows us to remove #include <uuid/uuid.h> from the public
API, giving us the freedom to change the underlying UUID implementation
later if necessary without breaking API.

All of the call sites already have a lvs pointer; there's no need to
look up the lvs by UUID again.

There are some upcoming changes which will deprecate
the old lvsuuid_blobid name in favor of an
lvs_name/lvol_name name where these names are
user-specified.
In preparation for this change, rename the previous
lvol->name to lvol->old_name. This will allow us
to add a new lvol->name but keep the original
old_name during the transition.

The get_lvol_stores RPC had typos in the free_blocks and total_blocks
fields (they were named "free_num_blocks" and "total_num_blocks", which
didn't match the names of the actual variables).

Currently there is no way to know total space availible on lvol store or
how much is left after creating lvol bdevs.
Four new fields should were added to get_lvol_stores:
- total number of blocks
- number of free blocks left
- block size (currently always 4096, but should be known to user)
- cluster size

New optional parameter -c or --cluster_sz in construct_lvol_store() RPC,
as well as in vbdev_lvol and lvol lib API.
This parameter allows to configure cluster size of blobstore that lvol store
is build upon.
When this parameter is not specified, default of 1GiB is used.
spdk_lvs_opts struct was created to facilitate any future options when
creating lvol store.
