This struct stores the slice of 'RoutinesSafeToIgnore' that are used as filters in `interestingGoroutines`. All package public functions for checking now immediately delegate to the `DefaultCheckConfiguration` which has the previous hard-coded list of values. This provides an extension point where a consumer of the library can extend the routines which are safe to ignore (i.e. explicitly allow a certain goroutine to leak) by either copying the DefaultCheckConfiguration and adding their own values (ideal), or by simply mutating the default value (less ideal).

馃憢 Hello鈥攖hank you for making this package, I was just about to start copying stuff out of net/http until I found it!
One thing which would be convenient for me is the ability to specify a certain goroutine is "not interesting"鈥攅.g. sometimes my code might be using some other package which starts some internal goroutine which by design runs forever. It would be nice if I could basically add it to the ignore list in the context of that particular test.
This PR attempts to achieve that by factoring out the slice of 'known disinteresting' values to a configuration struct, which can then be customised arbitrarily. The existing surface of the library doesn't change, as the package level functions now delegate to a package global default configuration.
