title: setting ttl of google bigtable using gcloud
body: <p>I was using aws dynamo db and used ttl property to delete record after some time 
  but now i am moving to GCP, </p>
  
  <p>In big table I can set expiration time for value hence I used Bigtable instead of Google Datastore</p>
  
  <p>I know I can set that using Go CLI using command</p>
  
  <blockquote>
    <p>cbt setgcpolicy my-table cf1 maxage=1d</p>
  </blockquote>
  
  <p>But I want to set it using gcloud cli or while creating using console or deployment manager</p>
  
  <p>Thanks in advance</p>
