Huawei SDSHypervisor uses a private key-value data protocal,
so we add a new connector inherited from InitiatorConnector
and implement connect_volume and disconnect_volume.
The connector uses sds_cli cmd to implement attach/detach/querydev vol,
sds_cli will be put to a specific dir and the path is registered as a
system environment variable when sds is installed.
