Added aws-lambda-java-events v2

Updated the aws-lambda-java-events packages. The following new events
were added:
* APIGatewayProxyRequestEvent
* APIGatewayProxyResponseEvent
* CloudFrontEvent
* CloudWatchLogsEvent
* CodeCommitEvent
* IoTButtonEvent
* KinesisFirehoseEvent
* LexEvent
* ScheduledEvent

Dependency management was also changed. Users must now supply the SDK
package if they are using an event that is connected to an SDK library.
These events are S3, Kinesis, and Dynamodb. See the documentation for
more details.
