Prometheus metrics shortcuts.

Aliases and requires respective metric modules so they are accessible without Prometheus.Metric prefix.

Allows to automatically setup metrics with @<type> attributes. Metrics will be declared in the @on_load callback. If the module already has @on_laod callback, metrics will be declared iff the callback returns :ok.
