Feat/schema validation (#5350) * Add the Schema type and a function to read it * Added a function to read a schema from a file * Check that values.yaml matches schema 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
