ton-node support prometheus metrics

[ton-devops]

Describe the issue
I would like to inquire about the timeline or plans for making Prometheus-compatible metrics available in the TON blockchain. Monitoring and metrics collection are critical for maintaining the health and performance of blockchain validators, and integrating with Prometheus would greatly facilitate this process.

What behavior did you expect?
I expected that the TON blockchain would either already have or soon introduce native support for Prometheus-compatible metrics, enabling seamless integration with existing monitoring setups.

What was the actual behavior?
As of now, there does not appear to be support for Prometheus-compatible metrics within the TON blockchain. This limits the ability to monitor validator performance and blockchain health effectively using industry-standard tools.

How reliably can you reproduce the issue, what are the steps to do so?
This is not a reproducible issue but rather a feature request. The current setup does not include Prometheus-compatible metrics.

What version of TON are you using, where did you get it (GitHub actions, self-compiled, etc)?
version - https://github.com/ton-blockchain/ton/releases/tag/v2024.08
