java: Maven plugin and archetype for the CDK

@arun-gupta proposed that we will write a maven plugin for the CDK that will make the CDK java experience more idiomatic:

• Maven archetype for cdk projects instead of cdk init -l java
• Maven goals for the various cdk operations such as synthesis, deploy, diff
• Remove the need for cdk.json, app.sh, etc.
• Don’t require to install node and the toolkit (we can do that by bundling the toolkit via the likes of pkg and then bundle into the Maven plugin for all architectures

+1 for Gradle as well as Kotlin for language. For orgs that are standardized on Gradle this is an impediment. Even better would be support for Gradle Kotlin DSL. I could see cli args being something like:

cdk init --language=java --build-tool=gradle dsl=kotlin

@eladb Gradle is pretty cool but Maven would capture significant part of the developer community IMHO. So for prioritization, start with Maven. If the code is modular then Gradle plugin would be just another wapper on top of the base code.
