Flowable base-image should use OpenJDK [enhancement]

Tag:

Your base image must not distribute Oracle's JDK/JRE, make sure your base image uses OpenJDK.

An excerpt from: Choosing the Base Image for Java 8

@Robinyo We will change the base image in the next weeks and will take this into account.
We will investigate what Java version and what distribution to use.
Thanks for the info.

We've updated the docker images to make use of adoptopenjdk/openjdk8:alpine-slim (https://adoptopenjdk.net).
Before the 6.5.0 release we plan to update to jdk11.
