  - ODLPARENT-137: restore the opendaylight prompt

    In Karaf 4.1 and later, it turns out that the prompt defined in the
    branding is overridden by the shell initialisation script,
    etc/shell.init.script, which defines its own prompt. This patch adds
    our own version of that script which disables the override.

    Thanks to Guillaume Nodet for figuring out where the override was
    coming from, and to Michael Vorburger for the initial investigation!
    See https://issues.apache.org/jira/browse/KARAF-5570 for details.
