[FEATURE] Make the UI more fault tolerant

[edenreich]

Summary

Networking issues can pop up everytime you lose connection the agent simply stops. Instead it should have a retry mechanism. To keep trying the request - configurable, I know we already have this feature implemented long time ago but we also need a visual in the terminal to let the user know it's currently trying to re-connect. A small hint in the status bar would be good.

Acceptance Criteria

• Reconnect in the status bar when losing internet connection or connection to the provider in general
• Reconnect attempt when we are getting any status code from the provider that is bad (>400 or <500 etc)
• Documentation is adjusted
• Higher connection re-try default instead of 3 times let's increase it to 5 - with the expo backoff
• It's tested
