Reduce size of cli docker image by removing tar (#214)

* Reduce size of cli docker image by removing tar

fixes: #213

Have the Gradle build unpack the distribution tar archive. This means there is no need to install tar or to have the tar file in the Docker image.

* oops - still need to copy the expanded archive in

* Switch to a smaller base image

fixes: #213
