ms: Add a first test to use all parts of the system

This is an interim solution but is bringing all parts together.
We will need to:

 * Abstract this into a base class
 * Be able to mix different tests without interfering with each
   other (e.g. 10k LU tests, 2k SMS sending)
 * The event loop will need to handle multiple timers/timeouts
 * Stats printing should print more information and test pass/fail
 * The test should quit early if everything has already passed
