fix(helm): add dry-run flag for init

fix(helm): use 127.0.0.1 instead of localhost

This switches the local chart repo to use 127.0.0.1 instead of localhost
so that the net library does not negotiate localhost to an IPv6 address,
which is known to cause issues in some Docker containers.

Breaking Change: When testing on a system that does NOT have IPv4
configured, this will break 'helm serve'. We estimate this will impact
none of the current user base.

Closes #1410

This adds a --dry-run flag to init, and causes the manifest file for
Tiller to be emitted on --debug. Together, this means you can do a
'helm init --dry-run --debug' and dump the Tiller manifest much as you
can with 'helm install --dry-run --debug'.

This does not require a server round-trip.

Closes #1417

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
