Bring 'node-inspect' (CLI Debugger) under the Foundation #190

As summarized in nodejs/diagnostics#67, work is underway to replace Node's current built-in CLI debugger (node debug) with a new one compatible with the new Inspector Protocol. @jkrems has an implementation at https://github.com/buggerjs/node-inspect and work has begun in nodejs/node#10187 to include this as a third-party dependency under "deps" in nodejs/node.

We'll likely also further integrate it into the standard Node binary so that node debug or node inspect work out-of-the-box as in the past, see nodejs/node#10187 for discussion.

Since the CLI debugger is a significant component of Node core, and because we'd like to facilitate broader and deeper work on this basic diagnostic tool, the @nodejs/diagnostics WG recommends that the TSC:

1. Bring node-inspect under the governance of the Node Foundation.
2. Bring the node-inspect repo into the nodejs GitHub org.

I believe all necessary prerequisites as described in TSC/Project-Lifecycle.md have been completed.

Thanks!
