Feat: decidim geo

[froger]

This PR add decidim-decidim_geo version 0.2.3. We join with this PR configuration to enable working better with the decidim-geo module:

• Add native dependancy libgeos-dev in the dockerfile See rgeo documentation
• Handle correctly deface in production with:
  1. a deface pre-compilation in entrypoint
  2. a DEFACE_ENABLE environment variable to enable dynamic deface resolution on demand
• update the package.json and yarn.lock
• update the Gemfile and Gemfile.lock

Some notes:

1. We have tested with our Decidim images (hfroger/decidim). It is possible that bundler version does not match the ones you use.
2. Running without libgeos-dev might just work, but we did not tests without a full-featured rgeos gem.

Thanks, Hadrien

Hey @froger

The Dockerfile in the root directory is the one currently used for deployment. The files in .docker are used for the docker-compose development workflow used by @carlobeltrame.

The deployment Dockerfile already includes the libgeos-dev package. I'll incorporate the other changes into that Dockerfile after merging and try to deploy it.

The feedback about the deface usage is very welcome. We haven't really done much with it yet.
