Automatically comment on initial onboarding ticket with all next steps

[kjduensing]

To incrementally make progress, we first must add a comment to the "kickoff" ticket with a list of steps required for the user to complete to move forward with onboarding. From here, the idea is to whittle away at this list by automating certain parts of it. This list should grow smaller the more steps we automate. The goal is to have only a single comment representing which step to take next.

See proposed onboarding flow for reference: https://app.mural.co/t/adhoccorporateworkspace2583/m/adhoccorporateworkspace2583/1658505157320/1c62a4c83f5e8d3e2669cacdfc7f7bcb5c18cbb8?sender=uead407ad0bba961db9834194

Consider using Github tasks list where appropriate https://docs.github.com/en/issues/tracking-your-work-with-issues/about-task-lists

done when:

• [ ] Comment is added to the ticket automatically after the user is added to the org successfully
• [ ] Comment includes the following steps:
  1. DSVA Slack Request
  2. Platform Orientation Request
  3. Instructions to get added to a github team
  4. SOCKS proxy request
  5. Console onboarding request (AMT allow list ticket)

"Comment is added to the ticket automatically after the ticket is closed successfully"

Why after the ticket is closed?

Why after the ticket is closed?

Updated the description to say "after user added to the org".
