Support login_hint for createLoginURL

[kenchan0130]

OIDC login URL can have a login_hint param.

If you already know the login ID, it improves the UX.

🤔

Since OIDCLite doesn't actually submit the URL to an ASWebAuthentication session, or other WebView... is there much benefit to OIDCLite adding that parameter instead of having your app do it before you pass the URL on?

We need to think about the responsibilities of the method before we talk about the benefits.

I think it depends on what you consider the responsibilities of OIDCLite's createLoginURL method to be.

If the method is responsible for issuing an OIDC login URL, then I think it should support the content based on the OIDC specification.

If there are no responsibilities, then my request itself should be withdrawn, as there is no obligation to absorb the specification in that method.
