AvgHistogram intends to aggregate raw values over the interval (minute, hour or day). When users query a value from
such a interval, an average over it will be sent back.

The acceptable bucket value should be a result from one of "increase", "rate" and "irate" query functions. That means
the value is the increase or per-second instant rate of increase in a specific range.

Example: "persistence_timer_bulk_execute_latency" is histogram, the possible PromQL format of acceptable bucket value
should be: "increase(persistence_timer_bulk_execute_latency{service="oap-server", instance="localhost:1234"}[5m])"
