Description of problem:

Using the --set flag in the CLI to change the value of a key nested in a dictionary overwrites the entire dictionary instead of updating just that value.

Version-Release number of selected component (if applicable):

v0.8.0-beta.2

How reproducible:

Always

Steps to Reproduce:

1. Clone https://github.com/konveyor/cf-k8s-helm-chart
2. Run the following command, pointing to the attached discovery manifest. Notice that we are overriding the app name:

kantra generate helm --chart-dir /path/to/chart/cf-k8s-helm-chart/java-backend/ --input /path/to/manifest/discover_manifest_app1.yaml --output-dir /path/to/output --set manifest.name=app2

Actual results:

All keys under manifest but name have been removed. Some templates that render depending on the existence of other nested keys under manifest don't render anymore. See attached file kantra-output.zip for additional details.

Expected results:

Only the value for manifest.name changes, leaving other values for the remaining keys under manifest intact.

Additional info:

I checked this with the helm template command, and it worked as expected. Here's the command I used:

helm template /path/to/chart/cf-k8s-helm-chart/java-backend/ --values /path/to/manifest/discover_manifest_app1.yaml --output-dir /path/to/output --set manifest.name=app2

Only the value manifest.name was changed, and the rest of keys under manifest kept their original values. See attacked file helm-output.zip for additional details.
