[CE-49] Adapt setup script to multiple linux distros

Linux distribution is extracted from /etc/os-release file where a line
ID= "distro" gives the mnemonic of the distribution

The main change in the script is to define installation procedure with
the proper packet manager (yum,zypper,cnf,apt-get..). The procedure will
install Docker, python-pip and eventually docker-compose

To test, a make setup was done followed by make start and the cello web
interface was verified as available through a browser . All tests are
conducted on VMs running on virtualBox

Testing has been done on the following distributions:
Opensuse (openSUSE Leap 42.2)
Fedora   (Fedora 25-1.3 server edition)
Debian   (debian 8.8.0)
Ubuntu   (ubuntu 16.04.2 server)
Mint     (linuxmint-18.1-cinnamon)
