As an evergreen engineer,
I want testresults to contain extra fields,
So that the hourly / daily test stats aggregations can use $merge as efficiently as possible.
- testresults will be amended to add the following extra fields:
- branch (the project)
- r (requester)
- display_name, the task display name
- execution_display_name, the execution task display name (can be null or missing).
- create_time, the task create time.
