Issue Summary

For any Server - Jira Cloud connected sites, it is possible to see user accounts with the below pattern:

migrate-jira-<Atlassian Account ID> 

This is reproducible on Cloud: Yes

Steps to Reproduce

1. Do a linking of the server site with the cloud site via CMAs. 
2. Atlassian creates system accounts as part of container token creation flow as container tokens are linked to the organization and not any single account. When the token expires, we don't do anything other than fail the validation of the token when it comes in. If you delete the container token, this will disable the system account in Identity systems.

Expected Results

At the expiry of TTL, the Atlassian account should get deleted along with expiry of token. 

Actual Results

Token expires but at TTL expiry, but the stale account is left behind.  

Workaround

Reach out to Atlassian support, on a case by case basis the users might be manually deleted.
