Re-figure out deployment process for individual API Umbrella components

[GUI]

The October upgrade to the system changed a lot, including how API Umbrella gets installed. While the new installation makes it easier to upgrade API Umbrella as a whole, one thing we've been missing since that rollout is an easy way to deploy some of the individual components of API Umbrella independent from new API Umbrella releases. We need better deployment functionality for the individual components so we can push live new features and functionality as we develop them, rather than trying to batching things into larger API Umbrella releases.

The fundamentals of how we will deploy this are still the same as before the October release (using Capistrano), but enough things have changed that I need to step through the deployment process again, and verify that deployments still occur without any downtime or dropping any connections.

Tested and new deployment seems to be working fine.
