Bug 2216704

Description of problem:
subscription-manager does not report 4xx messages sent by the Candlepin server. Instead, it shows the cached value and does not report the error status it has received.

Version-Release number of selected component (if applicable):


How reproducible:
100 %

Steps to Reproduce:
1. Spin up local Candlepin server
2. Register a new system to it
3. Restart the Candlepin server and make sure to redeploy the test data, to make the local certificate installed at the system invalid
4. Run 'subscription-manager status'

Actual results:

> +-------------------------------------------+
>    System Status Details
> +-------------------------------------------+
> Overall Status: Current
> 
> System Purpose Status: Not Specified

Expected results:

The 4xx status message is taken into account. One possibility is to do not display anything and only show the error message, as we usually do with error messages received from the server.

Another option is to include a message similar to the SCA one: show the table, but include additional information about the server reported failure.
