3.1.0

Docker Digest for 3.1.0: sha256:1656754cf4de441d85b08f584d9dcb095880d3bf250f05da26a03ff219d586c8

General:
    * Users of `mock_dynamodb2` should start using `mock_dynamodb` instead. 
      The `mock_dynamodb`-decorator has been repurposed to mock the latest version of DynamoDB, making the behaviour equivalent to `mock_dynamodb2`. 
      The `mock_dynamodb2`-decorator is now considered deprecated, and will be removed in the next major version.
* Similarly, users of the `mock_rds2` should start using `mock_rds` instead.
  The `mock_rds`-decorator has been repurposed to mock the latest version of RDS, making the behaviour equivalent to `mock_rds2`.
  The `mock_rds2`-decorator has also been deprecated, and will be removed in the next major version.

Internal Changes:
* We've upgraded our linting process to use Black 22.1.0, and have enabled more pylint rules.
Please continue to run make lint prior to creating a PR, to ensure any changes are formatted correctly.
