Adding a conditional to enable or disable bearer token in auto discovery

[reginaldomoura-jr]

This is to allow users to disable or enable the usage of sa bearer token in auto discovery, this was add on version 1.3.0, but users don't have a option to disable it if this is not needed. Unauthenticated services using Service Account without token or services not behind something like kube-rbac-proxy is returning 400 error.

Hi @petewall and @skl,

Can you help me to figure this issue?

We are not using the Service Account Tokens on our /metrics at this moment, and we are not using a proxy in front of this as well. Can we have a way to disable and enable the token path? I'm doing this proposal, on this MR. Please, let me know if I'm missing something.

Our services is getting 400, when auto discovery try to get the metrics.

Run helm-docs again and I think you'll be set!

My plan is to merge a few more and drop version 1.5 either today or Monday.

Thank you! This will help us to update our K8S Monitoring without any impact on metrics being scraped.
