Add deviceList parameter to connectStorageServer

[aesteve-rh]

Add a parameter to connectStorageServer, to send information to the host with all device guids (LUN wwids) that must be available on the host after connecting, specifically for iSCSI storage.

This will prevent proceeding with a connection before all the devices are available through dm-multipath, which could lead to errors afterwards (e.g., the VM not booting).

I kept this PR as a Draft since first we need to support the new parameter in the Vdsm side, before ready this branch up. Even after the Vdsm update, I am also a bit worried about the back-compatibility of this change.

Right now this is too big of a change, so let's drop it.
