Expected behaviour

Options specified in config should enable metrics collection.

[Metrics]
Enabled = true
EnabledExpensive = true

Actual behaviour

These options are ignored. Metrics server starts on 6060 port, but metrics are all zeroes, unless --metrics CLI arg is specified.

Steps to reproduce the behaviour

Add this lines to config.toml

[Metrics]
Enabled = true
EnabledExpensive = true
HTTP = "0.0.0.0"
Port = 6060

Start geth with flags --pprof --pprof.port=6060 --pprof.addr=0.0.0.0

Go to /debug/metrics/prometheus endpoint and all metrics will be zeroes.
