[library] Fix cobbler manifests to skip iptables in docker mode

[Matthew Mosesohn]

In relation to https://bugs.launchpad.net/fuel/+bug/1337288, we should run puppet with detailed-exitcodes and ensure that all puppet runs successfully without errors. iptables rules cannot be set in CentOS container, but it creates errors in Puppet.

    Cobbler docker mode fixes

    Skip cobbler::iptables in docker container for
    all docker modes and don't create profiles and
    distros during docker build.

    IPtables cannot be modified inside a Docker
    container. It creates errors that interfere
    with deployment.
