name limit.

Closes #1528

This documents YAML and provides information about how Helm and
Kubernetes interpret the YAML.

fix(tiller): return yaml parsing errors

feat(tiller): add source file to log entries

feat(gometalinter): Move to versioned releases

fix(helm): helm create will not overwrite existing files

feat(charts): Move bucket to domain from path

fix(tiller): show failed YAML

use openssl instead of shasum

fix(helm): respect dryRun opt in DeleteRelease

shasum is not on many platforms (like centos), use openssl instead.

gometalinter has moved to versioned releases. The latest of the v1
major versioned releases can be retrieved through pkg.in. This
change moves gometalinter use to the latest v1 release.

Downloading of charts and helm itself happened over http. This
change moves to use https as that is available with valid certs.

closes: #1519

When an install fails and --dry-run is set, return the broken YAML for
the user to debug.

Closes #1499

fix(helm): replace repo entry instead of duplicating

docs(tiller): add docblocks to public methods

A bucket name in the path can be migrated to a custom k8s domain
name. This is in preperation for that.

It will ignore files if they exist, and create files if they were
missing.
