title: Is there now a way to get "AWS region names" in boto3?
body: <p>Is there now a way in <code>boto3</code> to convert <em>AWS region codes</em> to <em>AWS region names,</em> e.g to convert <code>('us-west-1', 'us-east-1', 'us-west-2')</code> to <code>('N. California', 'N. Virginia', 'Oregon')</code>?</p>
  
  <p>I can get a list of <em>AWS region codes</em> with the following snippet:</p>
  
  <pre><code> from boto3.session import Session
   s = Session()
   regions = s.get_available_regions('rds')
   print("regions:", regions)
  
  $ python3 regions.py
  regions: ['ap-northeast-1', 'ap-northeast-2', 'ap-south-1', 'ap-southeast-1', 'ap-southeast-2', 'ca-central-1', 'eu-central-1', 'eu-west-1', 'eu-west-2', 'eu-west-3', 'sa-east-1', 'us-east-1', 'us-east-2', 'us-west-1', 'us-west-2']
  </code></pre>
  
  <p>Is there an equivalent snippet that would give me the <em>AWS region names?</em></p>
