aaa-cli-jar file size significantly reduced from 12 MB to 2.5 MB

aaa-cli-jar file size significantly reduced from 12 MB to 2.5 MB

it's now simply called aaa-cli-jar-*.jar instead of
aaa-cli-jar-*-jar-with-dependencies.jar

instead of the current 12 MB JAR file size, by assembling it using
maven-shade-plugin instead of the maven-assembly-plugin, which even
without minimizeJar leads to a 5.7, and with some clever minimizeJar
tweaking lets us make this just 2.5 MB.
