docs: Create the configuration for the local dynamodb instance.
  
  Region and AccessKeyId are determined as follows:
  1) Look at local aws configuration in ~/.aws/credentials
  2) Look at env variables env.AWS_REGION and env.AWS_ACCESS_KEY_ID
  3) Use default values 'us-east-1' and 'key'
  
  @param env - the process environment
  @param AWS - the AWS SDK object
  @returns {{endpoint: string, sslEnabled: boolean, region: string, accessKeyId: string}}
