Nicer error message for invalid token

[Jongy]

From the profiler server we get -

[2023-02-08 07:19:07,476] ERROR: gprofiler: Server error: Invalid API key

and the agent exits.

For the API server of glogger, we get this:

2023-02-08 07:19:08,434 - ERROR - Error posting to server

This clutters the log and hides the simpler error message. We should catch the error and replace with a nicer print. This requires changing granulate-utils' Sender - catch the 401 error and log a nicer message.

At the same time we can change the "server error: invalid API key" log to be CRITICAL.
