title: How to fix Powershell from stripping double quotes in a file
body: <p>I define a variable in Windows powershell like this </p>
  
  <pre><code>1.$LFILE=cat license.json
  2.echo $LFILE
     {
      "source": "ABCD LTD",
      "clientId": "EAL",
      "details": "Lenses",
      "key": "acfghkjhadasldas"
     }
  
  3.docker run --rm -d -p 3030:3030 -e LICENSE=$LFILE landoop/kafka-lenses-dev:latest
  </code></pre>
  
  <p>After i run this when i look at the license file inside docker container it removes the double quotes. </p>
  
  <p>When i check from inside the docker container this is what i see. if you see below the quotes are stripped off. </p>
  
  <pre><code>root@fast-data-dev / $ cat /var/run/lenses/license.conf
  {
    source: ABCD LTD,
    clientId: EAL,
    details: Lenses,
    key: acfghkjhadasldas 
  }
  
  io.lenses.core.license.LicenseException: Can not read the license 
  file:/var/run/lenses/license.conf
  </code></pre>
  
  <p>I tried to put $LFILE in single and double quotes.
  I tried to put the file name directly in docker command like this. still no luck.</p>
  
  <pre><code>docker run --rm -d -p 3030:3030 -e LICENSE="'$(cat license.json)'" landoop/kafka-lenses-dev:latest
  </code></pre>
