Job Summary Report

Depends on #3042687: Dispatch event upon job completion

This is a POC patch based on the work done in #3042687: Dispatch event upon job completion. Obviously we'd want to do something more meaningful with the report, but this shows the event subscriber will work.

For example, I just generated the following output:

{"total":26,"pass":0,"fail":26,"num_of_errors":52,"num_of_likely_problems":26,"num_of_potential_problems":104,"guidelines":{"BITV 1.0 (Level 2)":"BITV 1.0 (Level 2)"}

Okay #3042687: Dispatch event upon job completion has been merged in so we're good to proceed with this task further.

Still a work in progress but just uploading the latest version of the patch for visibility. This has obvious issues around code styling and things of that nature, but it does the necessary work of storing the results into the DB and provides a simple method for retrieving results.

The next step would be to take these results and output them somewhere. Maybe with a chart (although that might be a separate issue).

We may also want to think about notification services as well (probably should be handled in a separate issue).

This continues to be a work in progress, but here's the next iteration of this functionality. There's still a bit of room for cleanup and testing here, but just want to get the latest patch uploaded.

I provided an interdiff, but honestly it's long enough, reading the patch itself may just be the easier way of reviewing this.

This is a heavy change, but it should mostly be pretty straightforward.

So apparently WPA 8.x-2.7 was tagged, but never officially released. I just released the version, but given that dependency I'm gonna mandate WPA 2.7+ for this module in case anyone decides to use it who already has WPA installed.
