When using pkg/helm as a third party client, I am using chartutil.LoadArchive()
to load a chart from an io.Reader. After that is loaded I wish to install/update that
chart, however InstallRelease and UpdateRelease only accepts a path rather than
something of type *chart.Chart. This adds a new function called InstallReleaseFromChart
which allows one to load a chart separate from the path, then install said chart.

ref(kube): misc code cleanup

fix(kube): reap deleted resources during upgrade

feat(helm): add --reset-values flag to 'helm upgrade'

fix(helm) change name length limit to 63 for `helm create`

fix(Makefile): fix glob overriding packaged tar

Fix typo in help text for list cmd

since kubernetes 1.4, the upper limit for resource name is 63 characters,
so it is better to change the template when running `helm create` accordingly.

ref(kube): add Result to abstract a collection of resources

feat(helm): Create a Service definition for using Tiller in-cluster

feat(helm): Linter validations for Chart icon property

feat(helm): allow specifying --set multiple times

bugfix(tiller): replace + with _ in "helm create" template Chart version

Logging real name of the failing hook

The --reset-values flag on upgrade instructs Tiller to reset the
upgraded release to the chart's built-in values.yaml, and ignore the
last install's overridden values.

Closes #1569

Http client with TLS

fix(tiller): add missing name to status response

fix(tiller): don't update purged releases

feat(tiller): add {{.Capabilities}} object

fixes #1807

This adds the {{.Capabilities}} object to the template variables so that
chart authors can write charts that are aware of teh Kubernetes
capabilities of the current cluster.

Closes #1608

"spring" should be "sprig"
