Title: #625: [RFC] remote plugins: add option to force compat plugins

HonzaCholasta commented:
"""
* With `force_client_compat=False`, the benefit is the client API matches the remote server API, the drawback is `api.finalize()` does RPC calls and touches schema cache (i.e. the current behavior).
* With `force_client_compat=True`, the benefit is `api.finalize()` does no RPC calls nor does it touch schema cache, the drawback is that the client API is stuck at API version 2.164 (IPA 4.3.3).
* Schema download exists to support newer servers versions without having to update the client. Compat plugins exist to support older server versions which do not have schema support. (See http://www.freeipa.org/page/V4/API_Compatiblity.)
* *Optimistic try/fallback* is the current behavior which requires RPC calls in `api.finalize()` to detect the server's capabilities in order to reconstruct it's API locally. With this PR it's possible to skip this step and fall back to the behavior of IPA 4.3.3.
