CLI doesn't have intuitive message if it can't connect to MicroK8s

Bug Description

Right now the DSS CLI will show cryptic errors when it can't connect to microK8s. We saw this in #151

Specifically we saw messages like this:

dss status
[ERROR] Failed to retrieve status: [Errno 111] Connection refused.

The CLI should clearly expose that the issue is with talking to MicroK8s

To Reproduce

1. sudo snap install data-science-stack --channel latest/stable
2. dss status

Note that you should run those without initialising the DSS

Environment

Ubuntu 22.04

Relevant Log Output

[ERROR] Failed to retrieve status: [Errno 111] Connection refused.

Additional Context

From @misohu suggestion:

Part of this task can be to confirm with the UX team on how to best show the message, based on that we can fix it.
