Documentation: lack of important documentation in multiple areas

After reading the documentation I've noticed the lack of multiple important areas:

* Does it support any kind of multi-cluster support? E.g. Cross-Cluster Replication, Stand-By Clusters.
* Supported Hardware Architectures/OS combinations. From the Install page, it's not clear, which hardware architectures (like x86-64, ARM, etc.) are supported on which operating systems. If you have special requirements for the instruction sets (like SSE or AVX) - write about this in the documentation too. This information should be available in official documentation, not only in https://github.com/ytsaurus/ytsaurus/blob/main/BUILD.md
* Are there any recommendations regarding setup on cloud environments (like AWS/Azure/GCP/Yandex Cloud)? E.g. reference architectures, recommended hardware (e.g. recommended AWS EC2 machine type, disks, etc.), maybe even ready-to-use Terraform scripts? What about reference deploy architectures for on-premise installations?
* How could I install Highly-Available (HA) cluster? Are there any restrictions/recommendations regarding network latency between nodes? Recommendations regarding clusters across multiple Availability zones also would be useful.
* How to upgrade/downgrade YTsaurus? Does it support zero-downtime upgrades and downgrades? What about backward/forward compatibility between releases - what is the current policy?
* How to backup and restore YTsaurus? Are there any built-in integrity checks for the backup?
* How to monitor YTsaurus? Does it support any kind of integrated monitoring (like Prometheus endpoint, statsd integration, etc.)? If yes, how to configure it, and which metrics are supported?
* Would be great if you would be able to publish and maintain a public roadmap for the product.
* Is there any built-in benchmark utility like it's done in YDB (https://ydb.tech/en/docs/development/load-actors-overview)? Would be useful for benchmarking, choosing the proper cluster size, and performing PGO optimizations.
* Having public-available benchmarks (like https://benchmark.clickhouse.com/) also would be nice to have.
* Do you perform Jepsen-like tests? :)

I think this list could be somehow transformed into the documentation task epic and could be resolved step by step.

Thanks in advance!
