Adds Benchmark module to evaluate the SDK's first run performance

[vitorpamplona]

Fixes #1474, #825 and #1378, potential merger with #1414

Description Adds a simple benchmark module to run performance tests on the engine and workflow. The module is focused on the first-time runs, which drive most of the performance issues we are having. The tests must be run in order.

I am not convinced that yet another module needs to be added, but given our struggles with performance, it might be a good short-term investment.

Alternative(s) considered I tried building an app and a macro module, but I think this micromodule is a better approach.
