Creation of floating ip with new rbac policies fails

[Slawek Kaplonski]

When new api policies are used by setting:

[oslo_policy]
enforce_new_defaults = true
enforce_scope = true

Creation of new floating IP fails with error 500 returned. Neutron's server stack trace:

    Set system_scope='all' in elevated context

    In case when enforce_new_defaults is set to True and new policy rules
    are used, context.is_admin flag isn't really working as it was with old
    rules.
    But in case when elevated context is needed, it means that we need
    context which has full rights to the system. So we should also set
    "system_scope" parameter to "all" to be sure that system scope queries
    can be done with such elevated context always.

    It is needed e.g. when elevated context is used to get some data from
    db. In such case we need to have db query which will not be scoped to
    the single project_id and with new defaults to achieve that system_scope
    has to be set to "all".

    Revert "Set system_scope='all' in elevated context"

    This reverts commit 062336e59bb3d427bf4094779dc8e93d92c078d5.

    Now, we have proper fix for the system_scope='all' in elevated context
    in the neutron-lib so we can revert temporary fix made at the end of the
    Wallaby cycle.
