Gorka Eguileor 8e7ead7c27 LVM nvmet: Add support for shared subsystems
LVM target drivers usually only support unique subsystems/targets, so a
specific subsystem/target is created for each volume.

While this is good from a deployment point of view, it is insufficient
from a testing perspective, since it limits the code paths that can be
tested in os-brick.

Being able to test these 2 different paths in os-brick is very
important, because the shared case usually present very particular
issues: Leftover devices caused by race conditions between nova and
cinder, premature subsystem/target disconnection, not disconnecting
subsystem/target, etc.

Thanks to this patch we'll be able to increase the testing possibilities
of the NVMe-oF os-brick connector to cover combinations of:

- Different connection properties formats: old & new
- Different target sharing: shared & non shared

nvmet target driver: Added support for shared subsystems/targets using the
``lvm_share_target`` configuration option. Defaults to non shared, e.g.,
each volume has its own subsystem/target.
