EventBridge Bus Support

[jshlbrd]

Is your feature request related to a problem? Please describe.
The project supports the most common event-driven serverless services in AWS, but not the EventBridge bus.

Describe the solution you'd like
We should add a send transform for EventBridge that uses the PutEvents API.

Describe alternatives you've considered
N/A

Additional context
EventBridge is the only remaining event-driven service featured on the AWS serverless page that is not already in the project.
