[plirglo]

Describe the bug
I'm getting duplicated MOTD (Thea Head) when logging even on fresh installed machines.
Looks like this:

$ ssh operations@someip

How to reproduce
Steps to reproduce the behavior:

1. Install cluster
2. SSH to newly created machine(s)
3. check MOTD

Expected behavior
The Head should be printed only once

Environment

• Cloud provider: All
• OS: Ubuntu

Additional context
/etc/motd looks fine:

[operations@xxxx ~]$ cat /etc/motd

Currently, deployment creates /etc/motd file with the skull directly. I think is the wrong approach.
Ubuntu uses update-motd package and creates /etc/update-motd.d dir to store motd in right order. Creating eg. 99-epiphany script seems to be the right way.
In addition, I would add displaying epicli version at the end of this script.

(and yeah, we should get rid of this 💀 )

✔️ After logging in, Epiphany version is displayed. There are no more duplicate messages.
Tested on Ubuntu, RHEL and CentOS.
