feat: make LoadHTTPConfigFile set directory and move from tests file

[FUSAKLA]

Move away the functions from the test files since they are not only test helper.
For motivation, see prometheus/prometheus#11487

Also add setting directory cfg.SetDirectory(filepath.Dir(filepath.Dir(filename))) as used in Alertmanager see
https://github.com/prometheus/alertmanager/blob/1a9f55b939ab81b86428c013ae294ad80779c9b6/cli/config/http_config.go#L36

Prometheus does not use the LoadHTTPConfigFile function AFAIK, so the change in setting the directory won't break anything, hopefully.

Other possibility is to avoid setting the directory and fix this on the Alertmanager side outside the common library.
That might be safer (function is exported, so it could be breaking change for someone, possibly?)

Thanks, @roidelapluie, for merging!

Should I wait with using of the functions in Prometheus and Alertmanager for new release/tag of this repo?
Not sure what the release lifecycle is.
