The seemingly redundant `return filename, err` line is related to how
the name `err` is used throughout the function: there is a "global" (to
the function) `err` variable, as well as several locally block-scoped
ones. It took me hours to understand why my code did not work without
that line, but I decided not to clean up the `err` code in this commit.

These packages are generally used only for logic inside of Helm and

If a templates/ dir of a chart contained a subdirectory,
for example "templates/tests/test-db.yaml", an error was
being thrown on export due to missing the "templates/test"
directory prior to saving the template file itself.

Backport of https://github.com/helm/helm/pull/6010 to dev-v3 (the
description below is a copy-paste from the original v2 branch PR).
As https://github.com/helm/helm/pull/6016 is now merged to dev-v3, the
change is reasonably trivial.
This change is an attempt to address the common problem of json number
unmarshalling where any number is converted into a float64 and
represented in a scientific notation on a marshall call. This behavior
breaks things like: chart versions and image tags if not converted to
yaml strings explicitly.
An example of this behavior: k8s failure to fetch an image tagged with a
big number like: $IMAGE:20190612073634 after a few steps of yaml
re-rendering turns into: $IMAGE:2.0190612073634e+13.
Example issue: #1707
This commit forces yaml parser to use JSON modifiers and explicitly
enables interface{} unmarshalling instead of float64. The change
introduced might be breaking so should be processed with an extra care.
Due to the fact helm mostly dals with human-produced data (charts), we
have a decent level of confidence this change looses no functionality
helm users rely upon (the scientific notation).

This commit replaces usage of github.com/ghodss/yaml with it's forked
version maintained by SIG community. The replaced library has
low-to-none support activity unlike the latter. We believe the new
Helm branch could benefit from using the community-supported version on
a long-term run as yaml parser is a key component of Helm chart rendering
engine.
This commit locks sigs.k8s.io/yaml dependency version on 1.1.0 which
is backwards compatible with ghodss/yaml 1.0.0.
This change also resolves the outdated dependency version lock for
ghodss/yaml (currently 1.0.0) and makes it possible to port changes from
https://github.com/helm/helm/pull/6010 to dev-v3.

* Add the Schema type and a function to read it
* Added a function to read a schema from a file

This commit uses the gojsonschema package to validate a values.yaml file
against a corresponding values.schema.yaml file.
* Add functionality to generate a schema from a values.yaml
* Add Schema to Chart and loader
* Clean up implementation in chartutil
* Add tests for helm install with schema
* Add schema validation to helm lint
* Clean up "matchSchema"
* Modify error output
* Add documentation
* Fix a linter issue
* Fix a test that broke during a rebase
* Clean up documentation
* Specify JSONSchema spec
Since JSONSchema is still in a draft state as of this commit, we need to
specify a particular version of the JSONSchema spec
* Switch to using builtin functionality for file extensions
* Switch to using a third-party library for JSON conversion
* Use the constants from the gojsonschema package
* Updates to unit tests
* Minor change to avoid string cast
* Remove JSON Schema generation
* Change Schema type from map[string]interface{} to []byte
* Convert all Schema YAML to JSON
* Fix some tests that were broken by a rebase
* Fix up YAML/JSON conversions
* This checks subcharts for schema validation
The final coalesced values for a given chart will be validated against
that chart's schema, as well as any dependent subchart's schema
* Add unit tests for ValidateAgainstSchema
* Remove nonessential test files
* Remove a misleading unit test
The TestReadSchema unit test was simply testing the ReadValues function,
which is already being validated in the TestReadValues unit test
* Update documentation to reflect changes to subchart schemas
When creating a Helm chart for the first time, the assumption should be that the app version is also 0.1.0, implying this is for a new application.

Make template specific functions private to ensure they not misused and
make unit tests simpler. We may export the template helpers later if
needed.
This lays the foundation for the new chart pipeline.

`toYaml` utilized by `.Files` was introducing a new line. It is an issue since the new line is part of a functions output, it can't be whitespace chomped away so it would require a `trimSuffix "\n"` pipe. This commit trims one trailing `\n` from the toYaml output.
