Helm chart should make dex installation easier

[djkormo]

Maybe I'm wrong, but using dex for litmus and its configuration is out of scope of the litmus helm chart.
Documentation here https://docs.litmuschaos.io/docs/user-guides/chaoscenter-oauth-dex-installation Is not using strict declarative approach. My goal is to have helm chart as the source of configuration without additional imperative commands.

In values file for authServer the following variables should be added

authServer:
      
      env:

        DEX_ENABLED: "true"
        OIDC_ISSUER: REDACTED
        DEX_OAUTH_CALLBACK_URL: REDACTED
        DEX_OAUTH_CLIENT_ID: REDACTED
        DEX_OAUTH_CLIENT_SECRET: REDACTED
