flist used for ubuntu solution should not install openssh at startup

[zaibon]

It seems the startup script of the flist used for the ubuntu soltion (https://hub.grid.tf/tf-bootable/ubuntu:18.04-r1.flist) is

#!/bin/sh

apt-get update
mkdir ~/.ssh
mkdir -p /var/run/sshd
chmod 700 ~/.ssh
touch ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
echo $pub_key >> ~/.ssh/authorized_keys
apt-get install -y openssh-server
chmod 600 /etc/ssh/ssh_host_*
exec /usr/sbin/sshd -D

There is really no reason to install openssh-server every time a container start. Just include it into the flist. The chmod calls can also be done when you build the flist. SO the enrtrypoint of this flist could just be

#!/bin/sh

apt-get update
mkdir ~/.ssh
echo $pub_key >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
exec /usr/sbin/sshd -D
