cli: mimic behavior of BT1 when trying to attach to live session

In Babeltrace 1, when trying to attach to a LTTng live session the
`babeltrace` command would exit with status 0 (SUCCESS) if it
successfully connected to the relay daemon _even if_ it did not find the
requested session.

To mimic the behavior of BT1, we set the `session-not-found-action`
parameter to "end". This makes the message iterator of an lttng-live
component return a END status if the requested session is not found
on the relay daemon and makes the cli return gracefully with SUCCESS.
