Allow helm deployment to run in dev mode with tls enabled

[Ruddickmg]

Is your feature request related to a problem? Please describe.

I am testing a helm chart that I am deploying that has vault as a dependency. I would like to use tls while running the chart tests to ensure tls communication is working properly and covered in my integration tests. Currently with vault's helm values.yaml file, I am unable to configure vault to be both in dev mode and use tls.

Describe the solution you'd like

I would like to be able to configure vault to use tls while in dev mode via helm values.yaml.

Describe alternatives you've considered

Setting vault up in production mode might work, but would dramatically increase the complexity and set up of tests

Note:

This has been addressed here, but it does not seem like the same functionality has been made available in the helm deployment configuration (values.yaml)
