Export failure exception to influx db

What does this MR do and why?

As part of gitlab-org/quality/quality-engineering/team-tasks#1918 (closed), we want to try out using exception data to filter out certain failures before considering a test for the reliable bucket. As a first step to achieve this, we need to save exception data to influxdb which this MR does.

Also logs the file name that saves the test metrics.

Example where this was tried out: https://gitlab.com/gitlab-org/gitlab/-/jobs/4839207922#L284
