ntp install conflicts with existing ntp unit

[Behzad]

This doc is inaccurate in this way: The last section in NTP charm is wrong. There are two relations that proposed which are:
juju add-relation neutron-gateway ntp
juju add-relation ceph-osd ntp

but when yo run these two. there would be a conflict in using port 123. The reason is that there would be two instants of NTP in one machine.

This is a doc addition request:
I think it should be theses two relations:

juju add-relation neutron-gateway ntp
juju add-relation nova-compute ntp

We believe this is resolved in the latest ceph-mon and ceph-osd charm revisions. If you find that that is not the case, please re-open this bug with additional and updated information. Thank you.

This is less about the charms and more about the deployment.

I think the doc needs updating; however I think only a single unit of the ntp charm will be run on the machine, associated with both ceph-osd and neutron-gateway so triaging as low.

I have verified the issue with the latest charms (OpenStack Charms release 19.10).

I guess the fix is to not create the relation between neutron-gateway and ntp. I don't understand why that was done in the first place.

$ juju add-relation neutron-gateway ntp
