MINOR: contrib/prometheus-exporter: Add promex_metric struct defining a metric
This structure will be used to define a Prometheus metric, i.e its name, its
type (gauge or counter) and its flags. The flags will be used to know for
which entities the metric is defined (global, frontend, backend and/or server).
