Enhancement: Jobs that are re-submitted should display additional meta data

[constantine-nikolaou]

• Add ability to track how many times a job has been approved and on which channels it was shared.

• Display tracker data on job page for job owner, admins and members.

• Add a label on jobs when re-shared on slack, email and social media to distinguish new from old jobs.

• Experiment: Prevent automatically sharing job updates if job is re-submitted, instead allow sharing to be manually triggered by admins to avoid spam
