This commit introduces the support for the ETHERPAD_PLUGINS build parameter,
which contains a list of plugins to be installed while building the container.
EXAMPLE:
docker build --build-arg ETHERPAD_PLUGINS="ep_codepad ep_author_neat" --tag <YOUR_USERNAME>/etherpad .
Resolves#3618.
WORKDIR is also valid at build time, thus it makes sense to move it as towards
the top as possible.
This will come in hand in the next commits, when we will introduce support for
installing plugins while building the container.

[...] you should use WORKDIR instead of proliferating instructions like
RUN cd … && do-something,
which are hard to read, troubleshoot, and maintain.
Supervision/management should not be done from inside the container, but
externally, by container managers.
The container now simply runs node on server.js.
The logs are now readable from docker logs <container_name>.
This is a super simple start.
At minimum, configuration via environment variables (see #3543) needs to be
integrated in Etherpad to make this user-friendly.
Resolves#3524.
