Should not be a mutant for ConfigureAwait(false)

See original GitHub issue

We have various async code in our libraries like:

await doSomething(context).ConfigureAwait(false);

Stryker-mutator change the false flag to true but most of the time it’s for UnitTest purpose not interesting to change the flag to true.

We could check the name of a method before mutating it’s arguments. However we can’t be sure that if the name is ConfigureAwait it is an async configuration. If we exclude this method (or maybe even more) we could also exclude methods that should be mutated. How do you think we should handle this?

I have a working version under: https://github.com/anhaehne/stryker-net/commit/d73425afae78d21fa30cfeab640b7defbbc3ea78

The actual method filter logic is implemented here: https://github.com/anhaehne/stryker-net/blob/master/src/Stryker.Core/Stryker.Core/MutantFilters/IgnoredMethodMutantFIlter.cs

Console output could look something like this:
