Eric Fried 180c83b52b Centralize and clarify pip in the docs

Add a clarifying note about running pip (e.g. you might have to spell it
pip3) in a centralized place and link it from elsewhere. We should link
to this whenever we mention pip so we don't duplicate information.

Verify operation of the placement service.

Note

You will need to authenticate to the identity service as an admin before making these calls. There are many different ways to do this, depending on how your system was set up. If you do not have an admin-openrc file, you will have something similar.

Source the admin credentials to gain access to admin-only CLI commands:
```
$ . admin-openrc
```

Perform status checks to make sure everything is in order:

$ placement-status upgrade check
+----------------------------------+
| Upgrade Check Results            |
+----------------------------------+
| Check: Missing Root Provider IDs |
| Result: Success                  |
| Details: None                    |
+----------------------------------+
| Check: Incomplete Consumers      |
| Result: Success                  |
| Details: None                    |
+----------------------------------+

The output of that command will vary by release. See placement-status upgrade check <placement-status-checks> for details.

Run some commands against the placement API:

Install the osc-placement plugin:

Note

This example uses PyPI and about-pip but if you are using distribution packages you can install the package from their repository.
```
$ pip install osc-placement
```

List available resource classes and traits:

$ openstack --os-placement-api-version 1.2 resource class list --sort-column name
+----------------------------+
| name                       |
+----------------------------+
| DISK_GB                    |
| IPV4_ADDRESS               |
| ...                        |

$ openstack --os-placement-api-version 1.6 trait list --sort-column name
+---------------------------------------+
| name                                  |
+---------------------------------------+
| COMPUTE_DEVICE_TAGGING                |
| COMPUTE_NET_ATTACH_INTERFACE          |
| ...                                   |
