Add multiple executor and details about each executor test run

[LucaFavaretto]

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
