Prometheus monitoring for GitLab Pages

Closes #42

See merge request !11

Also fixed the dependencies, moved metrics to its own package and
updated the tests

This starts of the prometheus monitoring for GitLab Pages, and
resolves #42

Point to check:
- Are the metric names good, keeping Prometheus' conventions in mind?
- Golang, general style etc
- Shouldn't I do some voodoo magic to import this in the library?

Allow -listen-http, -listen-https and -listen-proxy to be given more than once
