Given we need to follow the Apache rule of not checking any binaries into the source code, Kafka has always had a bit of a tricky Gradle bootstrap. Using ./gradlew as users expect doesn’t work and a local and compatible version of Gradle was required to generate the wrapper first. This patch changes the behavior of the wrapper task to instead generate a gradlew script that can bootstrap the jar itself. Additionally it adds a license, removes the bat script, and handles retries. The documentation in the readme was also updated. Going forward patches that upgrade gradle should run `gradle wrapper` before checking in the change. With this change users using ./gradlew can be sure they are always building with the correct version of Gradle.
