Support info metric type #90

Hello,

Thank you for a great product, I use it on all my servers and VMs.

When trying to use https://github.com/prometheus/client_python#info metric type in an exporter behind expexp I get this error:

Mar 9 06:51:35 blackbox3 supervisord[64200]: exporter_exporter time="2023-03-09T06:51:35Z" level=error msg="Verification for module 'dnsexp' failed: Failed to decode metrics from proxied server: text format parsing error in line 20: unknown metric type \"info\""

I think it will be the same issue for https://github.com/prometheus/client_python#enum type metrics.

It would be nice to support both types.

I'll have a look to see if there are any updates to the client_go package that would help. In the mean time, you could turn off metrics verification in the config for that module.

Quack,

Got the same problem with the dovecot native metrics:

# HELP dovecot_build Dovecot build information--:--:-- --:--:-- --:--:--     0
# TYPE dovecot_build info
dovecot_build_info{version="2.3.19.1",revision="9b53102964"} 1

Thanks for the workaround. \_o<
