Deprecate blacklist and whitelist build options

Summary

This RFC proposes to deprecate the blacklist and whitelist build options, in favour of the exclude and include build options.

Motivation

In RFC 639, the exclude and include build options were introduced. These options provide exactly the same functionality as the blacklist and whitelist build options, but these new terms are more neutral.

RFC 639 was implemented and released in Ember CLI v4, which means we should be able to deprecate the old terms in favour of the new ones somewhere in the near future.

Transition Path

When either the blacklist or the whitelist build option is used, the following deprecation message will be triggered:

Using the `addons.blacklist` or the `addons.whitelist` build option is deprecated.
Please use `addons.exclude` or `addons.include` respectively instead.

Deprecation details:

Deprecation Guide

The addons.blacklist and the addons.whitelist build options are deprecated. Please use addons.exclude or addons.include respectively instead.

Before

// ember-cli-build.js

const EmberApp = require('ember-cli/lib/broccoli/ember-app');

module.exports = function (defaults) {
  const app = new EmberApp(defaults, {
    addons: {
      blacklist: ['ember-freestyle'],
    },
  });

  return app.toTree();
};

After

// ember-cli-build.js

const EmberApp = require('ember-cli/lib/broccoli/ember-app');

module.exports = function (defaults) {
  const app = new EmberApp(defaults, {
    addons: {
      exclude: ['ember-freestyle'],
    },
  });

  return app.toTree();
};

How We Teach This

At the moment, these options are not mentioned in the Ember CLI guides. This means, no documentation updates are required.

Drawbacks

• I cannot see any real drawbacks at the moment, the only user action that is required to resolve the deprecation is to rename one or two configuration keys

Alternatives

• I cannot think of any alternatives worth mentioning, keeping both sets of keys doesn't seem like a good idea, because they provide exactly the same functionality

Unresolved questions

• None at the moment
