This adds 'scripts/get`, which is a bash script for fetching and
installing the Helm client. It has the following features:

- It uses the GitHub API to discover the latest release
- It downloads the SHA256 checksum and verifies the binary using it
- It does basic tests on the installation

Add compression to configmap storage driver

Minor typo fix

fix(helm): finish repo index.html

docs(*): Minor corrections kebuctl commands in install.md

fix(helm): update helm commands usage text

This commit changes the configmap storage driver to compress
the serialized release before storing it as a base64 encoded string.
This change is backward compatible as it handles existing releases
gracefully by skipping the decompression step when the gzip magic
header is not present.

Fixes #1393

update helm commands usage text to reflect current state

Fixes #1266

fix(repo): ensure index generates in the right order

fix(tiller): ensure only the parent NOTES is used

fix(ci): ensure go packages are compiled before testing

Attempt for build speed record

fix(helm): respect kubeconfig default namespace

fix(tiller): delete all revisions with --purge

Previous versions of Helm had placeholder text in the index.yaml file.
This generates an HTML index for 'helm serve'. It also has a
refactoring of the server so that the server can be tested.

Closes #1397

closes: #1395

fix(helm): make 'helm repo index' generate the right index

fixes: #1396

This prevents the index command from recursing through directories.
Behind the scenes, it swaps out the repository logic for the index file
logic.

Closes #1328

fix(1357): print help text if revision is not specified

feat(helm): `--no-update` flag for `helm repo add`

fix(helm): show failed releases by default

doc(rollback): add docs for pre/post rollback hooks

docs(provenance): describe signature authority

fix(tiller): fix wording for a few errors

fix(tiller): fix nil pointers in error messages

This changes the wording of a log and an error message to make it
clearer what is happening.

There were a few places where error messages were accessing properties
of objects that were nil because of the error.

Closes #1374

For 'helm list', this now shows both deployed and failed releases by
default.

Closes #1387

fix(kube): find current resource by name and kind

fix(*): statically link cross builds
