Initial Support for ReplicatedMergeTree on S3

Initial support for ReplicatedMergeTree over S3 (it works in suboptimal way) #10126 (Pavel Kovalenko)
Initial implementation of ReplicatedMergeTree support for using Amazon S3 as a storage backend, enabling ClickHouse tables to store data on S3.

Why it matters

This feature allows users to leverage Amazon S3 for storing replicated data managed by ReplicatedMergeTree tables. It provides an alternative to local storage, facilitating scalable and durable storage options in cloud environments, although the current implementation works in a suboptimal way and may have performance limitations.

How to use it

To use this feature, configure a ReplicatedMergeTree table with S3-compatible storage by specifying the appropriate S3 storage settings in the table configuration. Note that this functionality is in initial development stage, so users should expect experimental behavior.
