provide TLS feature using Prometheus community exporter-toolkit web

[lucian-vanghele]

Proposed changes

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.

@lucacome sorry for delay. can you please check?

thanks for the comments. regarding exporter toolkit status please see https://github.com/prometheus/exporter-toolkit/issues/45 so I think experimental part is pretty obsolete by now. (and yes, the package is used in a lot of exporters)

I'll take a look at the other comments.
