Add info about the base image used and the github repo of
elasticsearch-docker.
Clarify that setting `memlock=-1:-1` is only a requirement when
`bootstrap_memory_lock=true` and the alternatives we document
elsewhere in docs for disabling swap are valid for Docker as well.
Additionally, with latest versions of docker-ce shipping with
unlimited (or high enough) defaults for `nofile` and `nproc`, clarify
that explicitly setting those per ES container is not required, unless
they are not defined in the Docker daemon.
Finally simplify production `docker-compose.yml` example by removing
unneeded options.

Elasticsearch runs as user elasticsearch with uid:gid 1000:1000 inside
the Docker container. Clarify that bind mounted local directories need
to be accessible by this user.

Today Elasticsearch allows default settings to be used only if the
actual setting is not set. These settings are trappy, and the complexity
invites bugs. This commit removes support for default settings with the
exception of default.path.data, default.path.conf, and default.path.logs
which are maintainted to support packaging. A follow-up will remove
support for these as well.

Fix the `Dockerfile` example in the `Customizing image` third configuration
method by adding the missing RUN instruction.

The reference for the jvm.options docs recently changed from
es-java-opts to jvm-options. This commit fixes a broken reference that
arose as a result of this change.
