Bug 1399791

Description of problem:
Incorrect command shown when extracting ironic password in 
The following doc has an incorrect command.

https://access.redhat.com/documentation/en/red-hat-openstack-platform/9/paged/red-hat-ceph-storage-for-the-overcloud/chapter-2-creating-an-overcloud-with-ceph-storage-nodes

The line in section 2.5 that reads:

export IRONIC_DISCOVERD_PASSWORD=`sudo grep admin_password /etc/ironic-inspector/inspector.conf | egrep -v '^#'  | awk '{print $NF}'`

should be:

export IRONIC_DISCOVERD_PASSWORD=`sudo grep admin_password /etc/ironic-inspector/inspector.conf | egrep -v '^#'  | awk '{print $NF}' | awk -F'=' '{print $2}'`

See this page for the correct command:

https://access.redhat.com/documentation/en/red-hat-openstack-platform/9/single/director-installation-and-usage/#sect-Completing_the_Undercloud_Configuration
