title: Cloud Foundry Maven Plugin proxy with authentication
body: <p>I am trying to deploy to Pivotal Web Services using the Cloud Foundry maven plugin.  I can deploy very easily with no network proxy in use, but when behind the network proxy I am unsure how to configure the plugin and I was not able to find a good answer while searching online.  Thank you for any help!</p>
  
  <pre><code>&lt;plugin&gt;
      &lt;groupId&gt;org.cloudfoundry&lt;/groupId&gt;
      &lt;artifactId&gt;cf-maven-plugin&lt;/artifactId&gt;
      &lt;version&gt;1.1.2&lt;/version&gt;
      &lt;configuration&gt;
          &lt;target&gt;https://api.run.pivotal.io&lt;/target&gt;
          &lt;server&gt;cloud-foundry-credentials&lt;/server&gt;
          &lt;org&gt;MindWaveService&lt;/org&gt;
          &lt;space&gt;development&lt;/space&gt;
          &lt;appname&gt;MindwaveServiceApp&lt;/appname&gt;
          &lt;url&gt;http://appurl-service.cfapps.io/&lt;/url&gt;
          &lt;memory&gt;512&lt;/memory&gt;
          &lt;instances&gt;1&lt;/instances&gt;
      &lt;/configuration&gt;
  &lt;/plugin&gt;
  
  &lt;proxy&gt;
    &lt;id&gt;optional&lt;/id&gt;
    &lt;active&gt;true&lt;/active&gt;
    &lt;protocol&gt;*&lt;/protocol&gt;
    &lt;username&gt;myUsername&lt;/username&gt;
    &lt;password&gt;myPass&lt;/password&gt;
    &lt;host&gt;myHostUrl&lt;/host&gt;
    &lt;port&gt;8080&lt;/port&gt;
    &lt;nonProxyHosts&gt;153.2.128.54|153.2.204.21|com.ups.*|10.244.223.27&lt;/nonProxyHosts&gt;
  &lt;/proxy&gt;
