feat: add a plugin system

[boneskull]

This adds a plugin system so we can separate things like rules (and eventually package manager implementations from the main codebase), and others can write custom plugins providing the same.

All rules have moved into the @midnight-smoker/plugin-default-rules package.

Limitations

Plugins currently cannot interact with each other nor declare dependencies on other plugins. Eventually I imagine someone might want to, say, override a rule.

Plugins cannot yet add package managers.

TODO

• List of plugins to load must be user-specified. Probably unwise to attempt automatic discovery (or make it opt-in). This will necessarily invoke multiple passes through options validation.
• Rules created by 3rd party plugins must be scoped to the plugin name.
• Need to assert the plugin name matches the package name.
• Docs
  • Plugin guide
  • Usage guide
  • Getting started guide
  • Rules reference
  • CLI reference
  • Config reference
• Anything else in the milestone

Future

• Custom script execution should be moved into a plugin, which means
• Plugins should be allowed to define command-line options
• And need to expose better hooks. Currently, Smoker is a vanilla EventEmitter, which is problematic if listeners are async.
