libStorage Refactor (DADD)

This patch is the basis for libStorage moving forward -- providing a
framework more consistent with an evolutionary take on the Docker HTTP
platform. Features include:

- Contextual logging
- Centralized types
- Generated server names
- Executor generation based on enforced Go interface types
- Librarification of the REX-Ray CLI
- Using `make run|run-debug|run-tls|run-tls-debug` to start
  a server directly from source, from the command line.
