AWS Serverless Example

Creating this as a placeholder to add an example to aws/serverless-java-container#128

instead of a shaded jar, it would be interesting to use the layered jars to take advantage of SOCI for container pulls and Lambda’s SnapStart

if it's helpful, we used to attempt to deploy our dropwizard app in lambda using https://github.com/trib3/leakycauldron/blob/v1.27.2822/lambda/src/main/kotlin/com/trib3/lambda/TribeServerless.kt -- cold start times were too slow to be useful so we deprecated & then deleted the code, but it may be a useful starting point for anyone interested, as with snapstart the cold start problem may be solved.
