Add Gitlab Job Event to the Webhook processor

Description of the feature request

Hi,
I need to start some quality pre-checks before sending data to Bitrise. Therefore, I would like to use the job event from gitlab and select the right trigger on Bitrise. Unfortunately, it is not available at this moment, therefore I will have to start the webhook manually from the job instead of using the gitlab dedicated feature.

Could you please add the job event to your webhook processor?

Use case / for what or how I would use it

I need to start Bitrise after another Job, therefore, I can’t use the default webhooks (PUSH, PR, TAG).
