Pass user context to virt driver when detaching volume
We need this in a later change to pull volume attachment
information from cinder for the volume being detached so
that we can do some attachment counting for multiattach
volumes being detached from instances on the same host.

Title:
detach multiattach volume disconnects innocent bystander
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) queens series:
In Progress
Bug description:
Detaching a multi-attached lvm volume from one server, causes the
other server to lose connectivity to the volume. I found this while
developing a new tempest test to test this scenario.
- create 2 instances on the same host, both simple instances with ephemeral
disks
- create a multi-attach lvm volume, attach to both instances
- check that you can re-read the partition table from inside each instance
(via ssh):
$ sudo blockdev --rereadpt /dev/vdb
This succeeds on both instances (no output or err message is
returned).
- detach the volume from one of the instances
- recheck connectivity. The expected result is that the command will now fail
in the instance where
the volume was detached. But it also fails on the instance where the volume
is still supposedly
attached:
$ sudo blockdev --rereadpt /dev/vdb
BLKRRPART: Input/output error
cinder & nova still think that the volume is attached correctly:
$ cinder show 2cf26a15-8937-4654-ba81-70cbcb97a238 | grep attachment
| attachment_ids | ['f5876aff-5b5b-45a0-a020-515ca339eae4']
$ nova show vm1 | grep attached
| os-extended-volumes:volumes_attached | [{"id":
"2cf26a15-8937-4654-ba81-70cbcb97a238", "delete_on_termination": false}] |
