    Update show_multiple_locations deprecation note

    Update logged text to indicate our intentions with respect
    to the show_multiple_locations configuration option, which
    has been deprecated since Newton and advertised as subject
    to removal in Pike. Also correct the misleading impression
    in the deprecation notice and earlier release notes that
    functionality that requires show_multiple_locations = True
    can be configured via policies at the current time. Also
    adds a release note to this effect.

    Not a straight cherry-pick. Changed the section of the
    relase note from 'upgrade' to 'issues' because this is more
    of a "known issue" in the stable branches.
