the `NewClient` method is called by the load test framework for each connection. This means that if multiple connections are instantiated, each connection will erroneously have its own UUID. This PR changes the UUID generation to happen at the _beginning_ of the script instead of on client creation so that each experimental run shares a UUID.
Caught while preparing the script for production readiness.

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

This pull request adds the loadtime tool. This tool leverages the tm-load-test framework. Using the framework means that the only real logic that needs to be written is the logic for Tx generation. The framework does the rest.
The tool writes a set of metadata into the transaction, including the current transaction rate, number of connections, specified size of the transaction, and the current time.
