fab create_install_repo_node doesn't work in 2.0

[Sylvain Desbureaux]

when launching fab create_install_repo_node:user@X.X.X.X, the result is the following:

user@fab:/opt/contrail/utils# fab create_install_repo_node:user@X.X.X.X

on line 508 of "/opt/contrail/utils/fabfile/tasks/install.py", "get_release()" method is asked. With get_release("contrail-setup"), it seems to work (contrail-setup seems to replace contrail-install-packages package in 2.0)
