event: separate metric types with Record methods

This is an alternative to having metrics as builders. Instead we use
the same builder for everything, but BuilderMetric takes a type that
is a pair of a Metric and Value. These pairs are created by the Record
metric of each Metric type.

This has the main advantage of separate builders -- typed metric
values -- without the downsides of repeated code, both in the
implementation and the client.
