latency_unit is read from cachet section

The code behaves differently than documented, the docs says, that latency_unit should be placed in endpoint configuration, but it is read from cachet section:

cachet-url-monitor/cachet_url_monitor/configuration.py

Lines 86 to 87 in ae0555c

    
           # The latency_unit configuration is not mandatory and we fallback to seconds, by default. 
        
           self.latency_unit = self.data['cachet'].get('latency_unit') or 's'

I can submit a PR once it's clear whether code or docs is the one to follow :-).

Good catch! The configuration should be per endpoint, as metrics are 1:1 with resources. I'll let you decide if you want to tackle this or should I do it :)
