`tools.prometheus.url` value is defined but not used in `kagent-tools` Helm chart

[MatteoMori8]

Hey 👋

I spotted something a bit odd with the helm chart and I thought I'll flag it

Description

The kagent-tools chart defines tools.prometheus.url (and related username/password fields) in values.yaml, but these values are never wired to the deployment.

Impact

Users attempting to configure Prometheus URL via Helm values will find it has no effect, leading to connection failures or confusion.

Environment

• kagent Chart version: 0.7.7
• kagent-tools chart version: 0.0.12

Also we need to auth against our thanos datasource - it has tenancy - so we need to be able to ship an Authorization header.
