39d2020392 Merge pull request #897 from smarterclayton/watch_starting_too_early 
Watch should start from next index when getting the initial state

befbf8466f Only write to etcd if values have changed 
This prevents certain loops from writing data to etcd every few
seconds (when data hasn't changed).

7c67cbff04 Watch should start from next index when getting the initial state 
Also, the fake response we return should have an Action that is
appropriate for the operation.

c21a0ca39f Breakup the registry package into separate packages. 
Currently all registry implementations live in a single package,
which makes it bit harder to maintain. The different registry
implementations do not follow the same coding style and naming
conventions, which makes the code harder to read.

Breakup the registry package into smaller packages based on
the registry implementation. Refactor the registry packages
to follow a similar coding style and naming convention.

This patch does not introduce any changes in behavior.

b986c520a7 Apply resource versioning to list extractions from etcd 
Set the resource version on lists of objects extracted from etcd to prevent
them from always being interpreted as new during updates.

c5630a9567 Watch delivers current state for resourceVersion=0 
Allows clients to get the current state without having to execute
a get followed by a watch.  Makes integration with action loops
much cleaner.

* Add labels selector (same as List)

* Add resourceVersion to let you resume a watch where you left off.

4448be2d95 Expose an Encoding/Versioning interface for use with etcd 
etcd_tools.go is not dependent on the specific implementation
(which is provided by pkg/api).  All EtcdHelpers are created
with an encoding object which handles Encode/Decode/DecodeInto.
Additional tests added to verify simple atomic flows.

Begins to break up api singleton pattern.

928092e79e Etcd watcher verification 
To make sure the etcd watcher works, I changed the replication
controller to use watch.Interface. I made apiserver support watches on
controllers, so replicationController can be run only off of the
apiserver. I made sure all the etcd watch testing that used to be in
replicationController is now tested on the new etcd watcher in
pkg/tools/.

2396bdfa1b Incorporate new types into versioned api system. 
* Made externalize/internalize generic to prevent boilerplate.
* Add fuzz testing.
* All objects pass fuzz tests now.
* This turned up some things we'll need to fix eventually. Left TODOs.

87fa19cdfe Remove extra test flags from all commands 
Currently all commands are being build with extra flags. The extra
flags appear because of a direct import of the testing package from
the fake_etcd_client.go source file.

Remove the direct import of the testing package. Add a tools.T
interface to support existing behavior. Also clean up two TODO items
by remove using of the expectError and expectNoError functions.

Fixes #579
