[Enhancement] Histogram aggregation should initialize Ranges lazily

Is your feature request related to a problem? Please describe

Currently, optimized histogram aggregation using multi range traversal initialized Ranges with all buckets eagerly. While for individual request, memory implications are small, it can starting adding up across all requests on a node.

Describe the solution you'd like

Given we process buckets one at a time, they can be initialized lazily avoiding unnecessary memory allocations. This should also allow to raise the number of buckets limit from 3k to 10k or more
