[keycloak-dev] Allow passing current locale to OAuth2 IdPs

[Johannes Knutsen]

We would like to have the user's current locale passed along to an
OAuth2 identity provider as a ui_locales parameter.
This would allow the user to select a custom locale on our Keycloak
instance and continue to have same locale on the external IdP.

Any thoughts on such a feature?

I have created an example implementation, see
https://github.com/keycloak/keycloak/compare/master...knutz3n:feature/pass_current_locale_to_idp,
and I will add tests and create a PR if you would like to merge it.
