nhcb: unit test framework to automatically generate custom histogram series from classic histogram series #13508
Description
Proposal
If the unit test has this kind of definition:
load 5m
testhistogram2_bucket{le="0"} 0+0x10
testhistogram2_bucket{le="2"} 0+1x10
testhistogram2_bucket{le="4"} 0+2x10
testhistogram2_bucket{le="6"} 0+3x10
testhistogram2_bucket{le="+Inf"} 0+3x10
testhistogram2_count{} 0+3x10
testhistogram2_sum{} 0+3x50
Then automatically create and store a custom histogram series called testhistogram2.
