Revert "Complete transition to an OpsBI sample"

This reverts commit c9886253a35869182d2207c52be56919af3e06da.
Let's try this again
More failure randomization

* Peaks in EndpointLoader.EndpointConfig once every hour
* VideoStore.Sales.SubmitOrderHandler throws a random exception every x messages but even more on peaks
* Exception thrown is also randomized
More custom checks
