Create a worker to handle test groups created on production

What does this MR do and why?

Temporary workaround for issue !82692 (merged)

It usually takes 7 days for groups created by e2e tests on production to be removed by APIs. This is causing ~5k groups for a single namespace on production that's impacting performance.

This MR serves as a temporary workaround to find groups that gitlab-qa is a member of and are marked for deletion, and remove them immediately.

Will also need an MR in https://gitlab.com/gitlab-com/gl-infra/k8s-workloads/gitlab-com to schedule the worker to run once per day.
