Prototype alternative deployment structure

Prototypes an alternative deployment directory structure for the
block-storage service to improve support for different build
configurations for different platforms. The new structure
reflects the three layers for app, infra and env to improve
reuse across multiple build configurations. The infra
(infrastructure) layer significantly improves flexibility
to realize app platform service dependencies in different
ways.
