Need class for OAuth client credentials in iOS/Android sdk

    Under Consideration
    ArcGIS Runtime SDK for .NET has OAuthClientInfo class to getting credentials with an OAuth app login.
    OAuthClientInfo class:

    Using this class, set ClientId and ClientSecret in properties, direct OAuth app login is possible from application.
    However, ArcGIS Runtime SDK for iOS and Android don't have a class for this authentication.
    Proxy servers etc. are necessary to OAuth app login in iOS and Android.

    iOS and Android SDK also need the class which can be authenticate at clientId and clientSecret.
