Gorka Eguileor 1cb6d3e1f1 Support shared_targets tristate value

Cinder microversion 3.69 adds an additional value to shared_targets
beyond true and false.  Now null/None is also a valid value that can be
used to force locking.

So we now have 3 possible values:

- True ==> Lock if iSCSI initiator doesn't support manual scans
- False ==> Never lock.
- None ==> Always lock.

This patch updates the guard_connection context manager to support the
3 possible values.

With this Cinder can now force locking for NVMe-oF drivers that share
subsystems.

     NVMe-oF connector `bug #1961102
     <https://bugs.launchpad.net/os-brick/+bug/1961102>`_: Fixed leaving
     controller devices (i.e., /dev/nvme0) behind on hosts.  Now NVMe-oF
     subsytems are disconnected when disconnecting volumes if the subsytem
     doesn't have additional volumes present in the host.
