Feature: support typescript project references

[mfogel]

This PR adds support for typescript project references.

To do so, it upgrades the following dependencies:

• ts-loader (to get Output while using project references is using the previous dependent package output instead of the current  TypeStrong/ts-loader#1114)
• fork-ts-checker-webpack-plugin (to get Plugin doesn't run for project references TypeStrong/fork-ts-checker-webpack-plugin#187)
• eslint (required by fork-ts-checker-webpack-plugin because of this check)

This PR includes a new test with a basic typescript monorepo configured with project references.

It's kinda a bummer the eslint upgrade is bundled into this PR. The only way I see around that would be to upgrade eslint & associated tools first as a separate step, and then address this PR/feature request.

Let me know if you'd like to see any fixes/changes or anything else I can do to help merge this in. Thanks a bunch for serverless-bundle, super helpful! Cheers.

Thanks for putting this together!

So from what I can see the main changes are to the forkTsCheckerWebpackOptions?

The rest of this change is just the ESLint major upgrade correct?

It sounds like we would need to do a major release for this change.

So we ended upgrading ESLint in this release.

Might make it easier to now support this feature. Can you fix the conflicts and I'll have a look?

Ah, great. That should simplify this PR a fair amount. I'll plan to update/rebase this PR on the latest on master over the weekend. Cheers

@jayair PR has been updated, should merge cleanly now
