Is your feature request related to a problem? Please describe.
Have a unified way to provide tls configuration by using exporter-toolkit from Prometheus community.(https://github.com/prometheus/exporter-toolkit/blob/master/docs/web-configuration.md). For this exporter is beneficial to rely on a big community. For teams using multiple exporters it helps to do things same way.
