Initial outline of opencord integration repo

- Vagrantfile to support standardized 'corddev' development environment
- Ansible playbooks to properly bring up devenv
- Gradle build structure
- Gradle plugin to manage docker-based workflow (pull, build, run, tag,
  push, etc.)
- Gradle top-level build file to allow pre-fetching and publishing
  component docker images. Supported main tasks: fetch, publish
- Example to how to manage 'as-is' upstream components
- A cleaner way of handling gradle rules
- Added initial content to README.md
- Added initial content to docs/quickstart.md
- Updated .gitignore
- Placeholder, parametric entry for deploy step
- Placeholder deployment profile config file (config/default.yml)
