Description of problem:

Unfortunately the placement osc part is not included and no seperate package is provided. This makes the subcommand `openstack resource provider list` unavailable, which is needed in many cases to inspect traits and allocations. An addition of that package would be very welcome, thank you.

Version-Release number of selected component (if applicable):
Any

How reproducible:
100%

Steps to Reproduce:

```
dnf in python3-openstackclient
openstack resource provider list
```

Actual results:

-> `openstack: 'resource provider list' is not an openstack command. See 'openstack --help'.`

Expected results:

```
$ openstack allocation candidate list --resource VCPU=1
+---+------------+-------------------------+-------------------------+
| # | allocation | resource provider       | inventory used/capacity |
+---+------------+-------------------------+-------------------------+
| 1 | VCPU=1     | 66bcaca9-9263-45b1-a569 | VCPU=0/128              |
|   |            | -ea708ff7a968           |                         |
+---+------------+-------------------------+-------------------------+
```
