Not all libs from externals end up packaged in my lambda function

[gligorkot]

I declare 3 packages in my externals list, but only 2 of them get included in the zip package of my lambda function.

The packages in question are:

• canvas
• chart.js
• chartjs-node-canvas

I believe the issue is that chartjs-node-canvas has canvas as a dependency, but chart.js as a peer dependency. When I run serverless package I get a warning

WARNING: Could not check for peer dependencies of chartjs-node-canvas. Set nodeModulesRelativeDir if node_modules is in different directory.

I believe if nodeModulesRelativeDir is exposed as an additional webpack config we can modify via serverless-bundle, I'd be able to configure it to correctly pull through the peer dependency chart.js as well.

I believe this was caused because my services are part of a monorepo. I've now exposed this setting via serverless-bundle config and it's working! I'll send a PR soon.
