This commit provides initial set of improvements to executing functions in AWS Custom Runtime
- Consistent invocation model for functional as well as @Bean configuration models via new CustomRuntimeEventLoop as well as AWSLambdaUtils
- Clean up classpath to decrease the size of the JAR/ZIP file
- Configuration simplification which no longer requires enabling of function exporter
It also allows user to define functions that rely on AWS types such as APIGatewayProxyRequestEvent
The existing invocation model remains in tact for the time being. Both invocation models are mutually exclusing in theit setup to avoid potential conflict.
