Add development environment

[tnation14]

Overview

As a part of the ongoing effort to break all GeoTrellis demos into their own separate services, this PR adds a Vagrant development environment with docker-compose, terraform, and awscli, and the Scripts to Rule them All.

Notable changes

• Move static/ and geotrellis/ into service/ folder
• Add Vagrant development environment with docker-compose, terraform, awscli
• Add docker-compose setup
• Fix geodocker ingest setup
• Replace Makefile with STRTA
  • Instead of having to run an ingest manually, scripts/update downloads pre-ingested data from S3.
• Speed up Docker image build process and shrink size
  • Add unnecessary files to .dockerignore

Fixes #35, #36

Testing

• Set up the development environment according to the instructions in the README.

• From inside the VM, start the service with ./scripts/server.

• You can also test the image I built with cibuild and cipublish:

  $ vagrant ssh
  vagrant@vagrant-ubuntu-trusty-64 $ eval "$(aws ecr get-login)"
  vagrant@vagrant-ubuntu-trusty-64 $ docker run -it -p 8777:8777 896538046175.dkr.ecr.us-east-1.amazonaws.com/gt-chatta:6de6ebe

  For both of these tests, the service should be available at http://localhost:8777

• To test the geodocker setup, follow the steps in the README
