Currently the @aws-cdk/aws-lambda-nodejs Functions default to OUTPUT hash type - however it'd be great to make this a configuration option to allow custom calculation of the hash to trigger a build on-demand.

Use Case

Improved deploy times when used with a Node-based async checksum algorithm for directories, or for manually triggering deploys in CI/CD based on external data.

Proposed Solution

As part of the NodejsFunction export props, re-add a bundling option for customizing the hash method & value using the existing @aws-cdk/aws-lambda#Function props. It would purely be a pass-through to the bundling.ts, optionally falling back to the current defaults - there wouldn't be any breaking changes.

This is a 🚀 Feature Request
