Fix bind mount volumes for novajoin containers

/var/lib/config-data/novajoin should not be bind mounted directly.
The way it works, is that a step 1 we generate all the config files with
Puppet and put the /etc/novajoin content into
/var/lib/config-data/novajoin and then filter out that is actually
needed by the containers into
/var/lib/config-data/puppet-generated/novajoin.

/var/lib/config-data/puppet-generated/novajoin will have
/var/lib/config-data/puppet-generated/novajoin/etc/novajoin with the
config files but it won't have the files excluded by container-puppet.sh
(e.g. host files, some CA/PKI files, etc).

In the container configs, we want to bind mount
/var/lib/config-data/puppet-generated/novajoin into
/var/lib/config-data/puppet-generated/novajoin:/var/lib/kolla/config_files/src
and when the container will start, Kolla will automatically copy the
content of
/var/lib/config-data/puppet-generated/novajoin:/var/lib/kolla/config_files/src
into / by deep merging; so /etc/novajoin will have the config files.
