Add 'Forced down' column in serivce-list

Starting from microversion 2.11,
the 'force_down' parameter is returned in the response of
the "List Compute Services" API (GET /os-services).

But the service-list command does not show the 'forced_down' parameter
in the result table.
So add the 'Forced down' column in the table.
