rCOMMa7374be8b830: [backup-service] Add blob client init function

Summary

Part of https://linear.app/comm/issue/ENG-2688/backup-service-reuse-single-blob-client-instance

Created a function that initializes a blob client instance. The connection is lazy-initialized so it won't be established until first use.

Depends on D6383

Test Plan

Backup service compiles.

19–20 ↗	(On Diff #21298)	I also consider connecting eagerly to catch connection failure early It would fail with a meaningful error when the backup service is starting - e.g. in cases when you forgot to start Blob service or provided invalid address. But on the other hand, I don't consider it the right way, as the connection isn't actually needed until first request.

services/backup/src/blob/mod.rs
19–20 ↗	(On Diff #21298)	Both approaches make sense. Also, we can't detect all the issues before the process starts, because the connection can be lost in the middle of the process.
