Rate-limited test routine

[adesjardins-stripe]

This PR introduces an entirely new test routine command.

Aside from a rate-limiter, this routine also includes support for:

• meta commands
• pre-test cache warming
• pre-generated keys
• expected value comparisons
• finite test runs
• deterministic test runs (rng seed parameter)
• run stats report

I also implemented some basic module support. Going one step further, vendoring the dependencies could be worth considering.

Ah wow I had completely forgotten about this PR; there's no activity on issues/pr's on this repo so I don't naturally land here much.

Did you ever end up using this?

Hey @dormando, it's all good. I would have bumped this if we needed action on it. In the end, we opted for some alternative testing procedures that were integrated within our in-house systems.

Thanks. That wasn't a great time for me so I wasn't able to keep us all in sync. I've been using mctester for the recent regression finding and need to decide how or whether to move forward with it for automation.
