`InstrumentationTest`: allow to record multiple markers
`InstrumentationTest`: allow to record multiple markers

Summary:
@public

Extends `InstrumentationTest` with the ability to record more than one marker.
Instead of overwriting any previously recorder marker, we collect them in a `std::deque`.

`std::deque` was chosen, because it keeps pointers to elements stable.
