Establish mechanisms to automate the installation of PJM on remote machines.

I did a first draft of the functionnality.
If someone want to test it, you can find it in the fabsim_bull_dev branch.

How to use it :
fab <remote_machine> install_app:name=QCG-PilotJob,external_connexion=yes
name=<name> --> Application name
external_connexion=<yes or no> --> remote machine has internet access or not

For now, the default installation is --user
Moreover if you set external_connexion=no , You have to add :
app_repository: "<Path/where/you/want/to/save/the/dependencies/archive>"
to your machine.yml or machine_user.yml

Let me know if you have any comments
