* Experimental: Serverless Trace target
The Serverless Trace target produces Serverless-handler wrapped entrypoints, but does not bundle all of `node_modules`.

This behavior increases bundling performance to be more akin to `target: 'server'`.

This mode is expected to be used with smart platforms (like [ZEIT Now](https://zeit.co/now) that can trace a program to its minimum dependencies.

* Use more generic variables

* Add asset relocator for production mode of serverless trace

* Verify Firebase compatiblity

* Revert "Add asset relocator for production mode of serverless trace"
