Add a metrics/collectors subpackage. When imported it pulls in and registers the fairly standard buildinfo, process and golang runtime collectors. Turn on the build info collector by default. Signed-off-by: Krisztian Litkey <[email protected]>
Simplify the policy-backend metrics collection interface, reducing it to a single GetMetrics() call and a returned Metrics interface which simply implements the collector- like Describe() and Collect() interfaces. Update policy implementations accordingly. Signed-off-by: Krisztian Litkey <[email protected]>

Simplify the policy-backend metrics collection interface, reducing it to a single
GetMetrics()call and a returnedpolicy.Metricsinterface, which simply implements the native prometheus collector interface withDescribe()andCollect(). Update policy implementations accordingly.
