'openstack service list' explanation references info not in output

[Daniel Axtens]

In the Ops Guide, in Lay of the Land > Servers and Services (pdf pg 28), there is the output of `openstack service list`:

+----------------------------------+----------+----------+
| ID | Name | Type |
+----------------------------------+----------+----------+
| 0a01b2d1ee5d4ce79ea65f6356a6fffb | nova | compute |
| 769eeea7aaef4724aa98376941d7c364 | glance | image |
| 87f4688f09104d81ab52661d74134652 | keystone | identity |
| 936cf7f450c2428e9e5746e0ea0a2cc7 | cinder | volume |
| c92b9bdcb42c48ddb7abd926d43999f9 | neutron | network |
| f633b72d040e46cb8700c62e82418b98 | cinderv2 | volumev2 |
+----------------------------------+----------+----------+

Immediately below that, the paragraph reads:

"The output shows that there are five compute nodes and one cloud controller. You see all the services in the up state, which indicates that the services are up and running. If a service is in a down state, it is no longer available. This is an indication that you should troubleshoot why the service is down."

I'm particularly confused by the line that says "You see all the services in the up state": I don't see an up state or a down state --- was there previously a column that said that? Or does it only show up if something is down? Either way, perhaps it could be explained more clearly.

    [ops-guide] Fix the incorrect command

    This patch https://review.openstack.org/#/c/351192/9
    updated "nova service-list" to "openstack service list". But its
    output did not match the contex. "nova service-list" should be
    replaced by "openstack compute service list --long"
