USER PROBLEM
^{What is the user experiencing as a result of the bug? Include steps to reproduce.}

• The user experience could be improved for the case where the user fails to provide the central endpoint for any command that requires connectivity to central
• sample command: podman run -it registry.redhat.io/advanced-cluster-security/rhacs-roxctl-rhel8:4.8.4 central login 
• returned error: ERROR: verifying login auth providers: requesting login auth providers: error when doing http request: dial tcp [::1]:8443: connect: connection refused

CONDITIONS
^{What conditions need to exist for a user to be affected? Is it everyone? Is it only those with a specific integration? Is it specific to someone with particular database content? etc.}

• missing endpoint information (env var or explicit command line parameter)
• no central instance listening on port 8443 on localhost

ROOT CAUSE
^{What is the root cause of the bug?}

• in case the endpoint information is not specified, roxctl uses localhost:8443 as default value

FIX
^{How was the bug fixed (this is more important if a workaround was implemented rather than an actual fix)?}

• (one possibility) - keep in the command context the fact that roxctl reverted to default, possibly use a shorter timeout in this case, and catch timeout/connection refused errors to return some more meaningful error than the raw technical error
