Tao Zhou d936a7a0e0 Add event interface to Gerrit ...

This is to solve problems like communicating among
Gerrit components, plugins and Gerrit, and plugins
themselves.

Original discussion and one classic problem to solve:
https://gerrit-review.googlesource.com/c/gerrit/+/242732

```
// pluginA
Gerrit.install(plugin => {
  // do something
  Gerrit.emit("event-name", {plugin: plugin});
});

// Gerrit
Gerrit.on("event-name", event => {
  // event.plugin should be pluginA
});
```
