title: What is the best way to solve `EntityAlreadyExists` error in terraform?
body: <p>I am using <code>terraform v0.12.6</code> and I run into many errors like:</p>
  <pre><code>Error: Error creating Security Group: InvalidGroup.Duplicate: The security group 'security-search-populate' already exists for VPC 'vpc-003e06e33a87c22f5'
      status code: 400, request id: 82acdc81-c324-4672-b9fe-531eb8283ed3
  
  Error: Error creating IAM Role PopulateTaskRole: EntityAlreadyExists: Role with name PopulateTaskRole already exists.
      status code: 409, request id: 49aac94c-d52b-11e9-a535-c19e5ed20660
  </code></pre>
  <p>I know I can resolve them by deleting these resources from AWS but I wonder whether there is a better solution?</p>
