add InstallReleaseFromChart and UpdateReleaseFromChart

fix(helm): Fake tillerHost at version cmd tests

Fix typo

Fix typo

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.

fix doc typo in FAQ

Version cmd tries to set up a tunnel at RunE instead of using the
PersistentPreRunE. That means that for each version test (3) it
tries to set up the tunnel. When running the tests on an internetless
or whithout a valid k8s environment, the tunnel will fail with a
timeout of 20 seconds, meaning that it will take 60 seconds to
run the test.

This commit adds a fake tillerHost so it will not try to setup the
tunnel.

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.
