enhancement(observability): update to the latest metrics release

[tobz]

Once a new minor release is cut upstream by metrics (including subcrates), we should update vector as well.

This will give us the ability to better describe metrics (without actually emitting them at a default zero value) ahead of time, as well as the ability to opt-in to using "metric handles", which provide a means to reduce the overhead of updating a specific metric by a significant amount. In most cases, updating metrics would be as fast as directly operating on an atomic integer.
