BREAKING CHANGE

Collectors/metrics registration should be done via prometheus_collector:register/1,2.

New

• It is also possible now to deregister individual collector via prometheus_collector:deregister/1,2
• Much effort has been made to cover code with type specs and please Elvis.
• New contrib module prometheus_http with default http request duration histogram buckets and
  status_class helper which returns response class from response code.

Special thanks to @yurrriq!
