Issue with setup on raspberry pi 3.

[faical-yannick-congo]

I have tested this on a hypriot os with docker swarm installed.
I actually had a raspberry pi cluster with docker swarm and wanted to turn it into a ec4docker elastic cluster. I recalled that some tools are not crosscompiled from apt-get: openssh-server is an example.

hi, @faical-yannick-congo

sorry but we are not experienced in raspberry pi. We have no way of testing it, by now.

Thanks @dealfonso . I have planned to dedicate sometime on it. Since i have a physical cluster of 4 RPi's and would like to try to setup an ec4docker elastic cluster. I will keep you posted if i meet an interesting sustainable pull request for you.
