Add multiple executor and details about each executor test run

**Is your feature request related to a problem? Please describe.**
We'd like to have a list of executors for an entire project test program and eventually the details about each executor run

**Describe the solution you'd like**
A list of executors instead of a single executor, and for each executor details about its run (e.g. percentage of failed/pass or number of test run)

**Describe alternatives you've considered**
None

**Additional context**
We have multiple test nodes that run tests and we need the results to be in the same report but with details about each test nodes trend

The issue names no files, tests, or entry points. Start by reviewing how the project currently represents a single executor and combines results from multiple test nodes. Done means one report can list all executors and show each executor's run details, including pass/fail percentages or test counts.
