[Feature Request] Client capabilities support

[henrik-me]

Smart Session Management (SSM) sometimes referred to as the long lived tokens (LLT) scenario require MSAL to allow developers to resolve challenges (formatted as claims request parameters) to be resolved silently rather than interactively. Current releases of MSAL assume that interaction is required whenever a claims request parameter is included in the request.

This change in behavior requires the client to indicate that it's aware of a new calling pattern relative to the use of MSAL.
