* Change ordering of config file vs env vars in Docker
Currently if you provide a config file it negates any settings set via environment variables.
This change allows use of a config file as a base and allow environment variables to override.
Additionally this allows dynamic features such as DRUID_SET_HOST to function correctly when a config file has been provided.
* Custom JAVA_OPTS should override service jvm.config
Currently `getConfPath` function returns an empty string for `indexer` service. So the config directory path for this service is not set properly when installed using docker environment.
Previously, when the Docker entrypoint script generated the config
files, it would append the configuration without including a newline.
This could result in incorrect configuration. This has been fixed by
always appending a newline before any configuration.

It is currently not possible to unset the druid.host property in the docker image to let Druid default to the canonical hostname. It always gets set to the container's IP address. Passing the override environment variable druid_host= unfortunately does not solve the problem, as this gets interpreted as empty string and does not let the default kick in.
This change adds the option to pass DRUID_SET_HOST=0 as environment variable to disable the default behavior, and allows passing a common runtime.properties file without druid.host.
* 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
* Add docker-compose and sample environment
