Small improvements to contribution docs
Move 'hack' to the less confusing 'project'

We might want to break it up into smaller pieces (eg. tools in one
place, documents in another) but let's worry about that later.

Proposal for an improved project structure.

Note: this deprecates the fine-grained, high-overlap cascading MAINTAINERS files,
and replaces them with a single top-level file, using a new structure:

* More coarse grained subsystems with dedicated teams of maintainers
* Core maintainers with a better-defined role and a wider scope (if it's
not in a subsystem, it's up to the core maintainers to figure it out)
* Architects
* Operators

This is work in progress, the goal is to start a conversation
