Helm chart - give an option to pass additional command line arguments

[gecube]

Hi!

As an user I want to pass an additional command line arguments to the headlamp deployment. Now there is no such an option.

Particularly I am interested in -insecure-ssl command line option for debug purposes

Alternative: make all command line options to have an ENV variable alternative and allow user to pass them to the deployment.
