Add initial docs for flake hunting.
Adding ListMinions() API to pkg/client.
Allow field/label users to get info from fields

Allows a consumer to get at the information stored in the field selector
for querying an underlying data store.  Not generic, but offers a
simple start.
Move EndpointsController to its own package

Avoids recursive loop with endpoint registry defined
Expose REST resource for endpoints and watch on services/endpoints

Will allow kube-proxies to listen on endpoints.
kube-proxy can read config from the apiserver

All clients that talk to a "master" as a host:port or URL
(scheme://host:port) parameter.  Add tests.
Merge pull request #899 from smarterclayton/watch_services_and_endpoints

Allow Kube proxy to watch for service/endpoint changes
Do not set IFS to the wrong value

The correct way to reset it to the default would be IFS=$' \t\n', but
there's no reason to assume a wrong setting here, in fact, nothing this
script does should depend on an IFS setting, so let's just drop this
line altogether.

Tested:
- Ran "release/build-release.sh <instance>" before and after this
  change. Compared the two trees for differences, only difference was
  the SHA1 in output/release/master-release/src/saltbase/pillar/common.sls

Fix commitFromGit -> gitCommit in release/build-release.sh

This caused Jenkins break on e2e-test because the version of server and
client did not match exactly, as the server was built without the
version ldflags.

Tested:
- Ran "release/build-release.sh ${instance_name}" and confirmed that
  output/release/master-release/src/saltbase/pillar/common.sls has the
  git version under version.gitCommit no longer version.commitFromGit.

Move go detection and environment setup into its own function

This way hack/config-go.sh can be used in environments where Go is not
available, such as running release/build-release.sh for Vagrant.

(The intention is to make config-go.sh a general library of helper
functions and import it from most other shell scripts.)

Fixes Issue #1057.

Tested:
- Built it and made sure it works.
  $ hack/build-go.sh
  $ output/go/bin/kubelet -version
  Kubernetes version 0.1+, build 0766e7a411c7-dirty

- Ran unit tests.

Merge pull request #1069 from filbranden/vagrant_config1

Move go detection and environment setup into its own function.  Fixes #1057.
Remove build dependency on `godep`

Instead of using `godep path`, we can simply set the GOPATH directly to
point to the Godeps/_workspace. We can still use `godep` to manage the
dependencies on the Godeps/ tree, but we don't need to have it available
for straight builds from git.

v2: Rebased and moved to inside kube::setup_go_environment() function.

Tested:
- Built it without godep in $PATH:
  $ hack/build-go.sh
- Ran unit tests without godep in $PATH:
  $ hack/test-go.sh
- Retested after rebase.
