[FEATURE] Make it possible to get the webhook URL from secret in the chart

[bitnik]

Description

In the current chart I don't see a way to get connector webhook URL from a secret. Or is there a way? Othwerise please make it sure that it can loaded/mounted from a secret.

Why is this needed?

Passing secret values in config yamls is not good.
