Better naming and better compile-time guarantees

• Renamed PrometheusCounter struct to PrometheusMetric (as per soloradish's suggestion in #4).
• Renamed render_counter function to render_sample (as per soloradish's suggestion in #4).
• Renamed attributes parameter to labels (as per soloradish's suggestion in #4).
• Changed the constraint in render_sample from std::fmt::Display to num::Num + std::fmt::Display for the value in order enforce at compile time the value as a number as per issue #5.
• Created the new enum MetricType and used instead of String in PrometheusMetric. This will enforce the use of valid metric at compile time.
