What does this PR do?

When the request to send traces fails, log more details of the error.

Motivation

This is similar to #1392. That PR only touched the debug-level log, so error details are not shown if log level is warn, causing difficulty in debugging support tickets such as SLES-2652. This PR add details to the error-level log message as well.

Additional Notes

How to test the change?

Not tested. Should be safe.

lgtm; theres a new PR title lint rule where titles need to be in the format of something like: type(team_name): description
