Updating parser for new directives

From Juniper website, you can download the XSD schema for the version of JunOS you want to target:

• Junos XML API
• Select your version
• Application Tools
• XML Schema for Configurator Data

Alternatively, you can retrieve the schema with Netconf:

$ ssh -Csp 830 JUNOS netconf < example/get-schema.xml | sed -n '/^<xsd:schema/,/^<\/xsd:schema/p' > junos-XXX.xsd

Put it in tmp/, update xsd_path in Rakefile and run:

$ bundle exec rake build:config build:rule

Alternatively, you may look in example/ for some prebuilt rules file. If you want to use them, copy one to tmp/rules.rb and run:

$ bundle exec rake build:rule
