fails fatally at startup iAND has misleading error message if update url is unreachable

[rob-1126]

This plugin breaks astro dev start AND use in Astronomer Software if the Airflow is working from a place where it can't access the update url.

Worked around in the image by setting

ENV AIRFLOWASTRONOMERUPDATE_INTERVAL=0

Here's the log that was sent. It's pretty scary and gnarly looking.

Can we just set a 2 second timeout on this url, catch basically any and all kinds of mischief from just that request, log a message, and keep-on-trucking?

I think this may turn out to be a different issue although it's possible that the error handling for one will handle the other as well.
