title: Specify VPC when creating RDS instance using boto3
body: <p>I can't seem to find the right argument to specify the VPC I need for creating the RDS, as the most relevant parameter I see is "VpcSecurityGroupIds", but it is definitely not the VPC, as trying to put my VPC id there outputs an error: <code>Invalid security group , groupId= &lt;vpc_id&gt;, groupName=.</code> What am I missing here?</p>
