Currently, Helm v2.5.1 is used, but this version is released in 2017 and a little outdated. To use the latest version of helm v2.x.x would be beneficial as we can use more useful Helm commands like `helm template`. This commit updates Helm version and stop using `helm lint` with `--strict` option because Helm v2.16.7 does not allow to use undefined values in values.yaml and the Helm upstream is now stopping using the `--strict` option.
