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.

* Add "--namespace" to helm lint
Keep lint syntax as close as possible to "helm install" resp. "helm
upgrade", so that one only needs to change the command.
See #2036
* Align lintCmd struct
* Add "--set" and "--values" to helm lint
Keep lint syntax as close as possible to "helm install" resp. "helm
upgrade", so that one only needs to change the command.
Closes #2495,#2036
* Reuse strict parameter, when rendering during lint
We want to see the rendering fail, if we missed a value, so we reuse
"--strict".
See #2495,#2036
* Fix lint unit test
See #2495,#2036
* Update docs
This adds the {{.Capabilities}} object to the template variables so that
chart authors can write charts that are aware of teh Kubernetes
capabilities of the current cluster.
Closes#1608
Long ago, Helm did not support cross-namespace installs. There was a
linter rule to catch this. When we changed the way Helm worked, we did
not remove the linter rule. This commit removes that linter rule.
Closes#1489
This adds a function engine.FuncMap that returns a function mapping that
better represents the functions passed to a template. The linting logic
is reconfigured to use this function instead of the sprig.FuncMap
function.
Closes#1366
The YAML validation was broken because the renderedContentMap has keys
with the path to the template including the chart directory, whereas the
linter was trying to access it relative from the chart directory.
For example, the hash key was `drupal/templates/deployment.yaml` but the
linter was trying to access `templates/deployment.yaml`. This commit
fixes the key used to access the rendered content.
Handle a previously unhandled error in the linter. This simply bails out
if a chart's values files do not parse.
Also, changed the implementation of CoalesceValues to return a map even
on error.
