NetApp SolidFire: Fix request errors while Element OS upgrade

Browse Source 
When Element OS is being upgraded, the requests received will
get exceptions as result, but the operation will normally succeed
a few attempts after.

This patch fixes this issue by adding the following exceptions to
our list of retryable exceptions in SolidFire driver:
    - xDBOperationTimeout.
    - xDBConnectionLoss.
    - xNoHandler.
    - xSnapshotFailed.
    - xRecvTimeout.
    - xDBNoSuchPath.
    - xPermissionDenied.
