Lambda Insights Support

Just curious if Chalice has any support to enable Lambda Insights? I think when you enable Lambda Insights using the AWS Console, then "Lambda adds the Lambda Insights extension as a layer to your function, and verifies or attempts to attach the CloudWatchLambdaInsightsExecutionRolePolicy policy to your function’s execution role." (see https://docs.aws.amazon.com/lambda/latest/dg/monitoring-insights.html#monitoring-insights-enabling-console)

I am not sure if the layer somehow can be added manually instead since that would already be possible.

Start with the AWS Lambda Insights enabling documentation linked in the issue and inspect how Chalice currently configures Lambda layers and execution-role policies. Determine whether the requested support is configuration, documentation, or both; done should mean a defined way to enable Lambda Insights through Chalice, with corresponding validation or documentation.
