title: setting a multi-line value in terraform variables
body: <p>I'm trying to deploy a beanstalk and use this as part of the <a href="https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/elastic_beanstalk_environment" rel="noreferrer">aws_elastic_beanstalk_environment</a> terraform resource:</p>
  <pre><code>  setting {
      namespace = &quot;aws:elb:policies:PublicKey&quot;
      name      = &quot;PublicKey&quot;
      value     = var.PUBLICKEY
  </code></pre>
  <p>The value of the <strong>var.PUBLICKEY</strong> should be in this format:</p>
  <pre><code>-----BEGIN PUBLIC KEY-----
  sajldlkuewindasmASL/aisudoiasumasdnowqeuoi@kajsdlkausKJDolkejpwr
  sajldlkuewindasmASL/aisudoiasumasdnowqeuoi@kajsdlkausKJDolkejpwr
  sajldlkuewindasmASL/aisudoiasumasdnowqeuoi@kajsdlkausKJDolkejpwr
  sajldlkuewindasmASL/aisudoiasumasdnowqeuoi@kajsdlkausKJDolkejpwr
  sajldlkuewindasmASL/aisudoiasumasdnowqeuoi@kajsdlkausKJDolkejpwr
  sajldlkuewindasmASL/aisudoiasumasdnowqeuoi@kajsdlkausKJDolkejpwr
  asdhjasd
  -----END PUBLIC KEY-----
  </code></pre>
  <p>May I ask if you have tried to set a variable with this kind of format? Or is terraform allow to use this kind of format as a variable on tfvars section?</p>
