    Allow admin user to get all tenant's floating IPs

    When getting floatingips by Nova API, the results will be filtered
    with the 'tenant_id'.
    So, we can only get the floatingips belonging the tenant of current
    context.
    When ceilometer invokes novaclient to list floatingips, it will get an
    empty list because the tenant is 'service'.
    we should allow an admin user to index all tenants's floatingip by adding a
    parameter 'all_tenants'.

    Part1:
        part1 try to implement this and part2 will remove the unused codes.
