Validation Options - Experiment 3 : Introducing new (optional) ClaimsWithOptions interface next to Claims

[oxisto]

This PR is part of a series of experiments, to see which options we have to implement validation options in a backwards compatible way. I want to get a fell about our options first and some feedback from the community, before we implement all desired options. I am looking to gather feedback here: #211

Option 3 is to create a new ClaimsWithOptions interface next to Claims, which provides an additional ValidWithOptions function in the claims to check validations with options. Valid is then redirected to ValidWithOptions

Pros:

• Should not break anything and seems to be transparent to the user

Cons:

• It's kind of a mess behind the scenes and it introduces a new interface that is sort of a workaround that we might want to get rid of in v5 again if we decide to break the api and just supply options to Valid directly.

Closing this for now as we are preparing for a new v5 api-breaking solution.
