Subject: [PATCH] Improved CLI connection error note.

[Feature]       CLI connection error note, and suggestion to launch
                vasum-server
[Cause]         Previous information was inacurate
[Solution]      Added proper error handling
[Verification]  Build, install, run cli/vsm when the server is not
                running
