Adds documentation for running `tiller` with the new secrets backend
added in #2721

Document how to add an image pull secret in Helm

Provide an example of how to take an image registry, user name, and password and prepare a Secret that can be used by a pod to pull a protected container image.

This feature enables users to specify more control over where Tiller pod
lands by allowing "node-selectors" to be specified. Alternatively, the
"--output" flag will skip install and dump Tiller's raw Deployment manifest to stdout so user may alter it as they see fit (probably with a JSON manipulation tool like jq).

Closes #2299

>0.0.0-a does not match pre-releases on 0.0.0 that start with a
capital letter or number. This has to do with the ordering of
code points. Numbers and capital letters come before lowercase
letters.

>0.0.0-0 should match all valid pre-releases on 0.0.0. According
to the spec, "Numeric identifiers MUST NOT include leading zeroes."
A 0 is also the lowest code point for all the allowed characters
in a pre-release

* helm create all defined template names should be namespaced https://docs.helm.sh/chart_best_practices/#names-of-defined-templates

* Update Doc

* Update example

This commit adds --kube-version flag to helm template. It allows you to
override the Kubernetes version used as Capabilities.KubeVersion.Major/Minor (e.g. 1.7).

easy copy/paste for those living on the edge :)

right syntax is helm.sh/hook-delete-policy according to commit 734b1245

This adds the functionality from the helm-template plugin to allow the
rendering of templates without Tiller.

Closes #2755

In this feature, we can use -f option with remote files, same as kubectl
accepts URLs. I add an option to send a 'get' request when read the local
file failed.

Closes #2642

When "helm.sh/hook-delete-policy: hook-succeeded" is provided in a hook's annotation, Tiller will automatically delete the hook after the hook is succeeded. When "helm.sh/hook-delete-policy: hook-failed" is provided in a hook's annotation, Tiller will automatically delete the hook after the hook is failed.

Closes #1769

This adds a new configuration option to Tiller to limit the number of
records stored per release.

Tiller stores historical release information (helm history, helm
rollback). This makes it possible to set a maximum number of versions
per release.

To enable this feature, use `helm init --history-max NNN`. Note that
because of the restrictions on Deployment objects, you will have to
re-install Tiller to add a limit.

Along the way, I found an unreported bug in the Memory storage driver.
This fixes that bug and adds substantially more tests to catch
regressions.

Closes #2332

Unsupported value: "alwaysPull": supported values: Always, IfNotPresent, Never
