Cannot run cinder-volume with SolidFire driver in active/active

[Mathieu Gagné]

When using SolidFire driver, cinder-volume cannot be run in active/active mode.

If the SolidFire account is created by the host "cinder01", we see this exception on the host "cinder02":
SfAccountNotFound: Unable to locate account cinder01-b3e8fa2d437e4befbd4e30f64e743c55 on Solidfire device

The SolidFire account is created with a prefix based on the hostname of the host running cinder-volume. We should be able to disable or override the prefix with our own to be able to run in active/active mode.

    solidfire: Add ability to override account prefix

    The SolidFire account is created with a prefix based on the hostname
    of the host running cinder-volume. This prevents cinder-volume from
    being run in an active/active setup.

    This patch introduces a new configuration option sf_account_prefix
    to override the prefix used when a SolidFire account is created.

    If sf_account_prefix is empty, no prefix will be added to
    the SolidFire account name when created.

    The default value is still the hostname.

    Fixes: bug #1179671

I would like this fix backported to Grizzly. Is it possible?
