Npm install fails with "sh: lerna: command not found"

[awssandra]

Problem:
Npm install can be used directly on github branches, forks and commits, no need to publish to NPM central.

Reproduction (on fresh machine):
npm install open-o11y/aws-opentelemetry-js

Command line output:

~/aws-xray-sdk-node-sample [ npm install open-o11y/aws-opentelemetry-js                                            

> aws-opentelemetry-js@0.10.2 postinstall /Users/mcmuls/aws-xray-sdk-node-sample/node_modules/aws-opentelemetry-js
> npm run bootstrap


> aws-opentelemetry-js@0.10.2 bootstrap /Users/mcmuls/aws-xray-sdk-node-sample/node_modules/aws-opentelemetry-js
> lerna bootstrap

Figured it out, lerna is required to manage the top-level dependencies, because each of those are packages are to be published separately.

So, it looks like we can't npm install separate packages via Github for multi-package lerna repos.
Reading:
lerna/lerna#2074
lerna/lerna#1033

Not sure how we're addressing this from a customer-usage perspective, if we're planning on publishing to NPM for preview.

As we published these packages separately and not the repository as a whole package; we don't encounter issue.
