Use new children-summary endpoint data to traverse job event tree

[keithjgrant]

SUMMARY

Updates UI to use the new children-summary endpoint (#11928) to determine number of child events & position in the tree. This greatly reduces the number of network requests made by the job output page for playbook jobs while expand/collapse is enabled.

This also addresses certain job events (such as Warnings) that do not fit into the parent/child tree structure of job events the way normal events do, which was breaking the UI's event lookup algorithm. The problem is these events don't have an parent_uuid field even though they might occur between two other events that share a parent. The children-summary endpoint provides a "meta_event_nested_uuid" object to place these events under the correct parent node so the lookup algorithm can work as expected.

This depends on #11928 and should not be merged until that PR is also merged.

Addresses #11818, #11765, #11647

hey @keithjgrant, I got this code locally. I did several tests.

I was not able to see the errors reported on the issues. Excellent job.

Also there was a big improvement on the number of requests being made.

Number of requests for job output using awx/devel.

Number of requests for job output using code.

We could remove the JobEventsAPI import from this test since we're no longer using it. What are your thoughts on removing the JobEventsAPI from our models completely? It doesn't look like we use that model now that we have this new /jobs/:id/job_events/children_summary/ endpoint.

I triggered the e2e tests.

Looks good! The above failed tests are unrelated to this work so it should be fine to merge

Thanks for the fix! Do we know when a new release with this PR will be cut?

The release cadence of AWX varies, however we try to release a new version of AWX every few weeks. If you feel comfortable running the HEAD of awx/devel then these changes will be immediately available.
