Get and keep IDA_LOGOUT_URI_LIST up to date

[robrap]

Acceptance Criteria

• Add comment near LOGIN_REDIRECT_WHITELIST (see notes)
• Communicate action needed (but not specifying who needs to take action).

Notes

We learned that commerce-coordinator was missing from IDA_LOGOUT_URI_LIST, and it was causing more user mismatch issues between JWT and session than necessary.

1. Do we want to get the rest of the IDAs into IDA_LOGOUT_URI_LIST?
2. Do we want to add a comment near LOGIN_REDIRECT_WHITELIST to remind people to also review IDA_LOGOUT_URI_LIST?
3. I found an updated https://2u-internal.atlassian.net/wiki/spaces/SRE/pages/19237450/Creating+A+New+Kubernetes+Django+Service#Configure-integration-with-the-LMS.
