[Fuego] [PATCH 06/11] Properly check install return code and abort in case of failure

[Guilherme Campos Camargo]

A new method 'install()' has been added to 'FuegoContainer' and the all
the docker_setup steps have been moved from the class __init__() to this
new method.

This will allow the 'main' function to check if install has failed
simply by inspecting its return.
