RFC: Moving ApprovedHosts to IList instead of IEnumerable

Request for comment @floyd-may

I'm looking at changing ApprovedHosts in FakeAuthOptions to IList instead of IEnumerable.

This is for parity with the Claims collection. (Also IList) to make the set up in StartUp easier (provides .Add()) Everything else stays the same and all tests seem to pass.

Branch: https://github.com/calebjenkins/FakeAuth/tree/dev/feature-13-evaluating-2.0
