This internal-only patch is to prevent Cinder's SanDriver from
attempting to use the Paramiko-based routines until the latter is
integrated into Solaris. It also provides a specific error in the case
where san_is_local=false is defined in the configuration and a driver
is specified that attempts to use that configuration (which implies,
again, an attempt to use Paramiko).
