Regenerating kubernetes.html
Copy docker client structs, adding yaml/json tags.

Use these in our v1beta1 package so that we can pass fuzz test encode/decode.
Move getting started guides to dedicated directory

The project README is getting quite large mainly because of all
the getting started guides embedded in the README.

Create the docs/getting-started-guides directory and relocate all
getting started guides. Update the README to link to each getting
started guide.
/api/v1beta1/operations was returning Not Found

Splitting an empty string returns []string{""}, not []string{}
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.
