The current methodology generated its own RS slice instead of using
a helper method that uses a `clientset`. This caused some issues where
`FindNewReplicaSet` always returned `nil`. This switches the method and
removes some unneeded API calls and code.

Closes #2426

* cleanup named imports

Rebase on kubernetes v1.6

Trigger deployment as success when new replicaSet has reached minimum you need which is number of replicas minus maxUnavailable

Closes #2162

This fixes a bug in which 'helm status' fails if any of the expected
resources are missing in Kubernetes. Now it prints a list of missing
resources at the end of the status report.

Closes #2118

Headless services (with `clusterIP` set to `None`) were reporting
as not being ready because they didn't have an IP address. This adds
a logic check to ignore those services.

When manifests do not change, they didn't get populated with the
latest label info from the API server and then panic'd. This resolves
that bug

Closes #2043

fixes #2006

* and comments

pulled logic out in pkg/releasetesting

* for WaitAndGetCompletedPodPhase

* This is a simple mvp which processes a test definition with the
hook annotation for test when you run `helm test [release]`
* helm client cmd, proto def, tiller logic

Adds `--wait` flag to helm that waits for all pods to reach a ready
state, PVCs to be bound, and services to have IP addresses

Closes #1805

Installs, rollback, upgrade, and delete now accept a `--timeout` flag
that allows the user to specify the maximum number of seconds that
any kubernetes command can take.

Closes #1678

It is unnecessary to create a namespace just to test that it exists.
Roles that don't have post namespace will error out even if the namespace exists
and it is possible to install the package anyway. This patch Gets a namespace and
only creates one if it doesn't exist.

  * Run gofmt on all changed files
    so they formatted properly now

 * Added pod restart for ReplicaSet
 * Added --restart flag for helm CLI for upgrade/rollback commands
 * By default, restart is false

 * Added pod restarting for
   - ReplicationController
   - DaemonSet
   - PetSet
