'openstack overcloud export ceph' --config-download-dir default should be /var/lib/mistral

[John Fulton]

The 'openstack overcloud export ceph' command works on ussuri and newer but requires the user to run the command like this when running the command on train:

 sudo -E openstack overcloud export ceph --config-download-dir /var/lib/mistral

This is because the --config-download-dir defaults to $HOME/config-download. This is an appropriate default for versions after train but the default for this parameter in train should be /var/lib/mistral.
