Build LogDog streaming support into the Recipe Engine. This includes:
1) First-class support for engaging a Butler instance and using its streams.
2) Integrating Milo annotation protocol construction and streaming as a recipe engine stream.
3) Sending subprocess data through LogDog instead of to STDOUT.
4) Disabling Annotee for these builds.
