NodeJS support for Lambda Layers

[ewindisch]

Lambda layers: Lambda can't find the file @iopipe/iopipe.js

A readme section was added describing how to manually integrate IOpipe to resolve this error, but we need to be able to integrate w/o code modifications.

I think this used to work... I'm not sure what changed, but we can no longer import the @iopipe/iopipe module as a handler directly.

@ewindisch Unfortunately the fix is that the Node.js runtime needs to perform a require.resolve against the NODE_PATH. This is functionally how the Python runtime works, where the runtime bootstrap sets the sys.path. I have no idea why the Node.js runtime isn't doing something similar.

This is not currently supported by AWS.

We will be switching to using a custom provider in the short-term:
iopipe/iopipe-cli#19

This issue should remain open until there is native support in the AWS runtimes.

The existing code works with custom runtimes. We will need to update documentation for layers as part of this, or another, issue.

https://github.com/iopipe/iopipe-cli will not be blocked by use of custom runtimes.

This is an issue with the runtime itself.
