Reduce image size for docker actions skeleton from 619.8MB to 86.78MB.
This makes the example docker image size equally smaller.
Use the base image for python actions but not Swift since the latter not yet ready for a diet.

Modify activation feed so that we grab next batch of messages and commit offsets immediately, essentially marking the activation as having satisfied "at most once" semantics (this is the point at which the activation is considered started); if the commit fails, then messages peeked are peeked again on the next poll.

While the commit is synchronous and will block until it completes, at steady state with enough buffering (i.e., maxPipelineDepth > maxPeek), the latency of the commit should be masked.

Add kafka test where we intentionally fail the commit and then confirm recovery.

(Unrelated by stashed in this commit: Ignore any db local ini in ansible directory in case there are more than one.)

Setup requires env.
.gitignore small cleanup.
Fix resource exclusions.

Support deploy.target in ansible deployment.
Restore build-with ant for redundancy.
Detect OS is GNU/Linux vs Mac OS X and set deploy target accordingly if not overriden with -D.
Allow tests with prefix when using ant by passing prefix to underlying gradle.

- Add Go CLI source code to OpenWhisk while leave Python CLI functionality intact

Moved Swift3 test, fixed formatting issues and extraneous white space in Swift code. Fixed up the CLI comments. Tweaked the Swagger docs more but these are a mess we need to fix more systematically.

Refactored Swift tests so that swift:3 extends swift tests. Rewrite Swift CLI tests in Scala and make Swift:3 test actually run the action.

Organize Docker to hit in cache on python layer.

adding roles for prereq and postdeploy as well as db role for local CouchDB.

issue #197 applied code review feedback: modularize deployment into individual playbooks, factored out initdb mode into db role, created separate roles for db providers which allows us to add more providers in the future, added user prommpt before dropping immortal db (can be overriden via cmd line param for travis)
