chore: Extend byte counters with a total amount of bytes since creation

[abies]

Description:
Possibility of retrieving the number of bytes read/written by a connection without stepping on the toes of metrics.

Proper way to do that would be probably redesigning metrics to NOT reset the counter, but hold a local copy of the last read count, it is a bigger change, and given that metrics are redesigned anyway, probably future work.

It is needed to implement per-connection throttling for sync/broadcast (#18762)

Fixes #26930

i would suggest calling it something like historicValue or nonResetValue
