See the list of configs supported by Prometheus atf88a0a7d83/discovery/nomad/nomad.go (L76-L84)- Removed "token" option. In can be set either via NOMAD_TOKEN env var or via `bearer_token` config option. - Removed "scheme" option. It is automatically detected depending on whether the `tls_config` is set. - Removed "services" and "tags" options, since they aren't supported by Prometheus. - Added "region" option. If it is missing, then the region is read from NOMAD_REGION env var. If this var is empty, then it is set to "global" in the same way as Nomad client does. See865ee8d37c/api/api.go (L297)and865ee8d37c/api/api.go (L555-L556)- If the "server" option is missing, then it is read from NOMAD_ADDR in the same way as Nomad client does - see865ee8d37c/api/api.go (L294-L296)This is a follow-up for8aee209c53Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3367
