Handed over from https://github.com/scylladb/scylladb/pull/20149
This adds minimal implementation of the start-restore API call.
The method starts a task that runs load-and-stream functionality against sstables from S3 bucket. Arguments are:
```
endpoint -- the ID in object_store.yaml config file
bucket -- the target bucket to get objects from
keyspace -- the keyspace to work on
table -- the table to work on
snapshot -- the name of the snapshot from which the backup was taken
```
The task runs in the background, its task_id is returned from the method once it's spawned and it should be used via /task_manager API to track the task execution and completion.
Remote sstables components are scanned as if they were placed in local upload/ directory. Then colelcted sstables are fed into load-and-stream.
This branch has https://github.com/scylladb/scylladb/pull/19890 (Integrated backup), https://github.com/scylladb/scylladb/pull/20120 (S3 lister) and few more minor PRs merged in. The restore branch itself starts with [utils: Introduce abstract (directory) lister](29c867b54d) commit.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
