Configure the UWS arq worker with Slack webhook support, and report unexpected job errors to Slack. Also report any errors updating the database as uncaught exceptions.
Previously, we were reporting them as transient, which seemed to result in pyvo retrying the request three times. Report them as fatal instead, as a more conservative assumption, to see if that prevents that behavior.
When reporting a failed task exception to Slack, add more metadata to make the exception more useful. Do not serialize the job parameters, though, since they may contain confidential information.
The required additional support for serializable exceptions has been merged.
Catch the error thrown when a cutout has no overlap with the specified image and return a better error message to the user. Flag this error to not be reported in Slack, since it's purely a user error.
