Subject: [PATCH] Add new exception to retryables in SolidFire driver

Newer versions of SolidFire Element OS introduce an
internal snapshot mechanism during cloning that also
includes a new exception (xNotReadyForIO).

This can be encountered when programmatically cloning
hundreds of large volumes. Typically this will succeed
on a retry of the clone command, so we should add this
new exception to our list of retryable exceptions in
the SolidFire driver.
