Description of problem:
After the switch to an external dracclient[1] the new python-dracclient package became a dependency to use the pxe_drac driver. Despite the package being added to the list of requirements[2], it doesn't seem to be getting installed and the Ironic8 gate is subsequently failing[3].

Version-Release number of selected component (if applicable):
openstack-ironic-api-4.2.2-4.el7ost.noarch
openstack-ironic-inspector-2.2.5-2.el7ost.noarch
openstack-ironic-common-4.2.2-4.el7ost.noarch
python-ironic-inspector-client-1.2.0-6.el7ost.noarch
openstack-ironic-conductor-4.2.2-4.el7ost.noarch
python-ironicclient-0.8.1-1.el7ost.noarch

How reproducible:
Very


Steps to Reproduce:
1. using rdo-manager install an undercloud
2. add `pxe_drac` to the `enabled_drivers` section of /etc/ironic/ironic.conf
3. $ sudo systemctl restart openstack-ironic-conductor
4. $ ironic driver-list

Actual results:
+---------------------+----------------+
| Supported driver(s) | Active host(s) |
+---------------------+----------------+
+---------------------+----------------+


Expected results:
+---------------------+-----------------------+
| Supported driver(s) | Active host(s)        |
+---------------------+-----------------------+
| pxe_drac            | localhost.localdomain |
+---------------------+-----------------------+

I can provide a live env. (for a day or so) to assist in debugging if necessary.
