Refactor for modular and pluggable design

- refactor logic of processing artifacts into their own classes
- introduce Container as the main class for bootstrapping and build a
  registry of handlers during boot to organize them by a hierarchy
  denoted by path
- adopt middleware like registration and invocation
- container.use(path, handler)
- container.run(context, done)
- allow more phases during boot
- boot is now asynchronous

@ -4,3 +4,27 @@ All breaking changes must be described here. When adding a new entry,
always describe the impact on users and instructions for upgrading
applications from 2.x to 3.0.
## boot.compile is now async and returns context with instructions
Users that uses `boot.compile()` in the following syntax would need to update
their implementation, it now calls callback function with `instructions` in
`context` object rather than synchronously returning instructions.
Before:
```js
var APP_PATH = path.resolve('../sandbox');
var instructions = boot.compile(APP_PATH);
```
New signature:
```js
var APP_PATH = path.resolve('../sandbox');
var instructions;
boot.compile(APP_PATH, function(err, context) {
instructions = context.instructions;
});
```
Please see [PR #181](https://github.com/strongloop/loopback-boot/pull/181) for full details of change.
