add separated runs by UUID (backport #9367) (#9380)

* add separated runs by UUID (#9367)

This _should_ be the last piece needed for this tool.
This allows the tool to generate reports on multiple experimental runs that may have been performed against the same chain.

The `load` tool has been updated to generate a `UUID` on startup to uniquely identify each experimental run. The `report` tool separates all of the results it reads by `UUID` and performs separate calculations for each discovered experiment.

Sample output is as follows

```
Experiment ID: 6bd7d1e8-d82c-4dbe-a1b3-40ab99e4fa30

        Connections: 1
        Rate: 1000
