    Reorganize guide on configuring a keystone SP

    The federation guide on configuring keystone as a Service Provider is
    disjointed and hard to follow. This patch reorganizes it as follows to
    improve the flow by first moving the instructions on creating an IdP,
    mapping, and protocol in keystone to the beginning, since all other
    steps in this guide depend on understanding what these objects are and
    deciding on a name for them, and second by consolidating instructions on
    creating role assignments into the section on mappings, since these two
    concepts are informed by one another and splitting them apart makes
    it difficult to mentally connect them. It also cleans up and clarifies
    some of the wording and pares down unnecessary tangents.

    Partial-bug: #1793374
