There was some ideas on reset/inc counter approach for monotonic metrics here: #128 (comment) . Maybe we should use this approach when #288 (review) instead of the current one? For example, when using prometheus the type of metric is shown in Grafana UI.

Luajit metrics should be gauge, because they're set in Tarantool, not metrics module.
I also refactor metrics.utils module and remove unused internal function
prefix_namefrom it's API.@DifferentialOrange, will it affect Grafana dashboard?
I didn't forget about
