doc: add technical values document

As part of the [next-10](https://github.com/nodejs/next-10) we found
we needed to capture the project's technical values/priorities as
a starting point before discussing key technologies/areas for the
next 10 years of Node.js

This is a first cut that the team put together. The discussion
took place in a few meetings as well as this
[PR](nodejs/next-10#11). We believe the doc
should live in the core node repository as it is intended to
reflect the agreement of the collaborator base.

I think this is a good starting point but we also
acknowledge that only a small subset of the Node.js collaborators
have participated/commented so far. This PR should be a good
way to get additional review/input from the larger set
of Node.js collaborators.

+# Technical values and priorities
+
+The project uses these technical values to establish priorities and guide
+collaboration.
+
+## Values and priority level
+
+* Priority 1 - Developer experience
+* Priority 2 - Stability
+* Priority 3 - Operational qualities
+* Priority 4 - Node.js maintainer experience
+* Priority 5 - Up to date Technology and APIs
+
+## Value descriptions
+
+### 1 - Developer experience
+We value ensuring that developers are productive and enjoy developing
+with Node.js. Some key elements of this include:
+* Approachability (both technical and community)
+* Great documentation
+* Bundling friction-reducing APIs and components, even though
+  they could be provided externally
+* Enabling/supporting external packages to ensure overall developer experience
+
+### 2 - Stability
+Whenever possible, we seek to insure that currently-working code continues to
+work. We seek to keep the trust of developers and end-users. Therefore, we value
+stability.
+Some key elements of this include:
+* Backwards compatibility
+* Stable releases on a predictable schedule
+* A strong safety net, including testing how changes
+  in Node.js affect popular packages
+* Careful consideration of what goes into long term support (LTS) releases
+
+### 3 - Operational qualities
+We value keeping Node.js safe, performant, and lightweight.
+We value enabling the ability to investigate and debug problems in
+development and production. Some key elements of this include:
+* High throughput (speed)
+* Fast startup
+* Small binary size
+* Small memory footprint
+* High-quality debugging tools
+* Robust diagnostic tools (profilers, etc.)
+* Responsible security practices
+
+### 4 - Node.js maintainer experience
+We value the productivity and happiness of the Node.js maintainers.
+Some key elements of this include:
+* Approachability of the codebase
+* Good internal documentation and guides
+* Low-friction policies and processes
+* Good CI and tooling to make maintainers productive
+
+### 5 - Up to date Technology and APIs
+We value providing developers with modern APIs and technologies
+following existing standards whenever possible.
+Some key elements of this include:
+* Participating in standards work and organizations
+* Web API compatibility
+* Supporting and exposing new technologies and standards through early adoption
