CI / CD - Staging implementation

Continuous Integration and Continuous Deployment to (at first) a Staging Environment.

• Setup develop / master branch (develop for CI / CD to Staging, master for production)
• Setup VPS for runner and deploy
• Write & Test runner script
• Add DNS entry for staging-blog.hive.io

Envisioned breakdown of how this runner works:

1. Builds image on CD VPS based on latest commit
2. Pushes images to "unlisted" registry (S3) - anyone can pull an image from here.
3. Kill previous image on CD VPS
4. Run image on CD VPS (staging-blog.hive.io)
5. Nginx / letsencrypt reverseproxy to the condensor port(s) of the latest build
6. Tests?
7. If fails somehow, revert to previous committed image? (point 3)
