This modifies `helm status` to return info about deleted and failed
releases. We do our best to retrieve info for releases that were
partially deployed.

fix(tiller): truncate release name returned from moniker

This is a minor refactor to move a leftover from Ancient Helm into the
current design. Specifically, the code to install Tiller from the Helm
client is now in `cmd/helm/installer`.

Closes #1033

feat(*): add 'helm list --all' and related flags

This adds support for the following 'helm list' flags:

- all: show all release types
- deleted: show deleted releases
- deployed: show deployed releases
- failed: show failed releases

These flags can be toggled. Only '--deployed' is turned on by default.

On the server side, Tiller's list function can now filter based on a
slice of release.Status_Code filters. While the client only supports a
subset, the server supports all known release.Status_Code types.

Closes #973

This allows the following commands to accept more than one argument on
the CLI:

- helm fetch
- helm package
- helm delete

Closes #1100

ref(kube): delete skips IsNotFound errs

Currently, delete returns an error if a resource is not found.
That is a bit confusing because if you delete something that
is not found, the end state is not really an error. The end
state is what you wanted to do in the first place. This type
of error is not propogated from the kube client but it is logged
in tiller.  We could also change this to keep returning errors
(even the not found) and filter it out in the release server.

Add purge option for completely remove a release from tiller

ref(*): return resource update errors

Resolves #1058
