[Bug 1823200] Please test proposed package

[Corey Bryant]

Hello Eric, or anyone else affected,

Accepted cinder into train-proposed. The package will build now and be
available in the Ubuntu Cloud Archive in a few hours, and then in the
-proposed repository.

Please help us by testing this new package. To enable the -proposed
repository:

  sudo add-apt-repository cloud-archive:train-proposed
  sudo apt-get update

Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-train-needed to verification-train-done. If it does
not fix the bug for you, please add a comment stating that, and change
the tag to verification-train-failed. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance!

Bug description:
  The ScaleIO driver uses the backend storage login and password for
  authentication for connections to the volume as well as the management
  API.

  https://git.openstack.org/cgit/openstack/cinder/tree/cinder/volume/drivers/dell_emc/scaleio/driver.py?h=13.0.4#n176

  https://git.openstack.org/cgit/openstack/cinder/tree/cinder/volume/drivers/dell_emc/scaleio/driver.py?h=13.0.4#n229

  This has a few serious implications:
  a) A user can create a volume, retrieve the username/password from that volume, and use it to connect to a different tenant's volume.  Most drivers create per-volume credentials.

  b) A user can create a volume, retrieve the username/password from
  that volume, and use it to connect to the ScaleIO management API and
  presumably do lots of things they shouldn't be allowed to.  Most
  drivers create credentials for volumes that are independent of the
  management credentials.

  c) If the password is changed on the backend ScaleIO volumes that are
  currently being used stop working, because Nova stores the old
  password in its block_device_mapping table.  (Not a security problem
  other than the fact that it prevents rotation of passwords, but
  definitely a bug.)

  Parts of these issues are separately being looked at in bug 1736773,
  (which generally advises that in some clouds, only Nova should be able
  to see connection info, not end users) but the situation there is
  worse for the ScaleIO driver because most drivers only put
  usernames/passwords in connection_info that are usable for a single
  volume, not for the storage backend itself.
