The EventEmitter class conflicts the EventEmitter module

[koshigoe]

Issue description

The event_emitter gem implements EventEmitter module.
The aws-sdk-core gem implements EventEmitter class.

• https://github.com/shokai/event_emitter/blob/a01fe7850bd48995bd424146263b6ddb45fd763e/lib/event_emitter/emitter.rb
• https://github.com/aws/aws-sdk-ruby/blob/821a66f491c33ecffdcbfcbfddbb8dcf9be2d630/gems/aws-sdk-core/lib/aws-sdk-core/event_emitter.rb

So, I can't use event_emitter together with aws-sdk-core.
(TypeError: EventEmitter is not a module)

Gem name ('aws-sdk', 'aws-sdk-resources' or service gems like 'aws-sdk-s3') and its version

• aws-sdk-core 3.21.1
