Milestone M31 updates

Let's go through what we got done in Milestone M31 (Feb 24 - Mar 09).

Bug fixes:

• We found the /services_health_check Endpoint giving timeout errors again despite fixes last time. We debugged and found that for the EUI check, if the EUI is down, it might take 60 seconds before returning a timeout. In general, we decided to fix this for all the apps, and we added an option to add a timeout for such additional services API checks in neeto-commons-backend. Now, any app with an additional service to check can add a timeout; failing that, the API request will fail fast, not triggering NeetoCommonsBackend::Failures.

Upgrades:

• We migrated the packages-upgrade script in neeto-course-site to NeetoCi from github-actions.
