storwize svc driver needs to avoid SVC CLI shortcut

[Alan Jiang]

For SVC storwize driver, the SVC cli is invoked directly by using cli shortcut instead of a svcinfo or svctask wrapper.
The shortcut is h/w model dependent. The safer way to invoke svc CLI is to wrap SVC cli with svcinfo and svctask command and handle the SVC error code if the command is not supported.

svcinfo -? and svctask -? can dump all the supported cli on a given SVC.

For example, on V3700, lslicense is not supported, and some older SVC f/w version doesn't support lssystem

Those SVC CLI error will cause storwize_svc to throw exception and break cinder when managing some SVC model.

This bug is related to bug 1163754, which is one instance of a command that is not supported in all firmware versions. They can be fixed together.

    Fix incompatible Storwize/SVC commands.

    Inconsistencies in the command line syntax between Storwize/SVC
    models and firmware versions caused driver failures. This patch
    makes commands compatible to fix driver crashes on the V3700 and
    controllers with firmware version 6.3.
