Description of problem:
In 1.2.3. Content Delivery Server, we have the following text:

"During configuration, you specify the CDS’s directory where packages are synchronized. Similar to the RHUA, the only requirement is that you mount the directory on the CDS."

Please add the fact that if NFS is used, rhui-installer can configure an NFS share on the RHUA machine to store RPM packages and Yum repository data, and also a directory on the CDSes where the NFS share will be mounted. The following rhui-manager options control these settings:

    --remote-fs-mountpoint        the filesystem location where the remote filesystem share should be mounted (default: "/var/lib/rhui/remote_share")
    --remote-fs-server            remote mountpoint for a shared filesystem to use;
                                  for example, nfs.example.com:/path/to/share (default: "nfs.example.com:/export")

If these default values are used, the `/export` directory on the RHUA and the `/var/lib/rhui/remote_share` directory on each CDS are identical. For example, the `published` subdirectory has the following structure if Yum, Docker and OSTree repositories are already synced:

[root@rhua ~]# ls /export/published/
docker  ostree  yum

[root@cds01 ~]# ls /var/lib/rhui/remote_share/published/
docker  ostree  yum
