title: cf push -p incorrect usage
body: <p>I am trying to push a package on IBM cloud</p>
  
  <pre><code>cf push “Backoffice” -p target/Backoffice.war
  FAILED
  Incorrect Usage. 
  [...]
     -p   Path to app directory or to a zip file of the contents of the app directory
  </code></pre>
  
  <p>where </p>
  
  <pre><code>cf -v
  cf version 6.33.1+c77e55743.2017-12-15
  </code></pre>
  
  <p>I don't know what to do since my call with the "-p" option is inline with the doc. I am new to cloudfoundry / IBM Cloud.
  I don't have a manifest.yml  file.</p>
  
  <p>Then I do  (and I get):</p>
  
  <pre><code>cf logs "VCBackoffice V2"
    " maximum number of connection retries reached "
  </code></pre>
  
  <p>Can you help me identifying the problem(s) ?</p>
