    Reload iptables after purging rules, add rsyslog to post_start_hooks

    In some cases, rsyslog would only unmasquerade UDP connections
    and not TCP connections, causing issues with deployment.

    This commit includes fixes for purging old iptables
    rules that run into race conditions, as well as a fix
    for grep to include '--' to handle strings that
    start with dash.
