There aren't any changes in this patch that improve Java 11
compatibility; these changes have already been done separately. This
patch merely updates documentation and explicit Java version checks.
The log message adjustments in DruidProcessingConfig are there to make
things a little nicer when running in Java 11, where we can't measure
direct memory _directly_, and so we may auto-size processing buffers
incorrectly.
* switch builder image to smaller "slim" debian base
* use built-in pyyaml
* skip various build checks to speed up compilation
* create user/group in target image directly
* Remove mysql database connector from container image
See discussion on `dev` mailing list from 2019-03
around [docker
build](http://mail-archives.apache.org/mod_mbox/druid-dev/201903.mbox/browser)
Remove the mysql database connector from the container
image in favour of solely the postgresql connector.
Instructions are present in distribution/docker/README.md
for someone to re-add if they need.

* Add sample Dockerfile for mysql using pre-built upstream
* Add docker container for druid
This container is an 'omnibus' (since there is such a high
overlap with the various services). It includes all contrib
extension as well as the msql connector.
It is intended to be run as `docker run NAME SERVICE`
(e.g. docker run druid:latest broker)
* Add Apache license header
* Resolve issues from Pull Request review
* Add comments at top of script per PR comments
* Revert BUILDKIT. Not available everywhere.
* Don't set hostname, allow default (IP)
Some environments (e.g. Kubernetes Deployments) don't resolve
hostname to IP.
* Switch to amd64 glibc-based busybox from 32-bit uclibc
* Override service-specific configuration
* Replace MAINTAINER w/ LABEL
* Add mysql connector to application classpath
This works around issue #3770https://github.com/apache/incubator-druid/issues/3770
