Fix junos unique routing-options container

[ckishimo]

In the default test case in the openconfig-network-instance you can find different routing-options containers for the AS, the router-id and the static routes, like:

  <routing-options>
    <autonomous-system>
      <as-number>65000</as-number>
    </autonomous-system>
  </routing-options>
  <routing-options>
    <router-id>1.1.1.1</router-id>
  </routing-options>
  <routing-options>
    <static>
      <route>
        <name>10.0.0.0/24</name>
        <qualified-next-hop>
          <name>192.168.100.100</name>
          <metric>100</metric>
        </qualified-next-hop>
        <qualified-next-hop>
          <name>192.168.100.101</name>
          <metric>200</metric>
        </qualified-next-hop>
      </route>
      <route>
        <name>10.100.0.0/24</name>
        <qualified-next-hop>
          <name>192.168.100.200</name>
        </qualified-next-hop>
      </route>
    </static>
  </routing-options>

However there should be a unique routing-options container, like:

  <routing-options>
    <autonomous-system>
      <as-number>65000</as-number>
    </autonomous-system>
    <router-id>1.1.1.1</router-id>
    <static>
      <route>
        <name>10.0.0.0/24</name>
        <qualified-next-hop>
          <name>192.168.100.100</name>
          <metric>100</metric>
        </qualified-next-hop>
        <qualified-next-hop>
          <name>192.168.100.101</name>
          <metric>200</metric>
        </qualified-next-hop>
      </route>
      <route>
        <name>10.100.0.0/24</name>
        <qualified-next-hop>
          <name>192.168.100.200</name>
        </qualified-next-hop>
      </route>
    </static>
  </routing-options>
