these unused includes are identified by clang-include-cleaner. after
auditing the source files, all of the reports have been confirmed.
please note, because `mutation/mutation.hh` does not include
`seastar/coroutine/maybe_yield.hh` anymore, and quite a few source
files were relying on this header to bring in the declaration of
`maybe_yield()`, we have to include this header in the places where
this symbol is used. the same applies to `seastar/core/when_all.hh`.

Fixes#20716
Propagates abort source in task object to actual network call,
thus making the upload workload more quickly abortable.
v2: Fix test to handle two versions after each other
Task manager GET /status method returns two counters that reflect task progress -- total and completed. To make caller reason about their meaning, additionally there's progress_units field next to those counters.
This patch implements this progress report for backup task. The units are bytes, the total counter is total size of files that are being uploaded, and the completed counter is total amount of bytes successfully sent with PUT requests. To get the counters, the client::upload_file() is extended to calculate those.

* github.com:scylladb/scylladb:
backup_task: Report uploading progress
s3/client: Account upload progress for real
s3/client: Introduce upload_progress
s3: Extract client_fwd.hh
This is continuation of previous patch, this time also update tests that
wait for specific message in logs (to make sure injection handler was
called and paused the code execution).

Do it by passing reference to s3::upload_progress_monitor object that
sits on task impl itself. Different files' uploads would then update the
monitor with their sizes and uploaded counters. The structure is
reported by get_progress() method. Unit size is set to be bytes. Test is
updated.

This is to export some simple structures to users without the need to
include client.hh itself (rather large already)

before this change, we only record the exception returned
by `upload_file()`, and rethrow the exception. but the exception
thrown by `update_file()` not populated to its caller. instead, the
exceptional future is ignored on pupose -- we need to perform
the uploads in parallel. this is why the task is not marked fail
even if some of the uploads performed by it fail.
in this change, we
- coroutinize `backup_task_impl::do_backup()`. strictly speaking,
this is not necessary to populate the exception. but, in order
to ensure that the possible exception is captured before the
gate is closed, and to reduce the intentation, the teardown
steps are performed explicitly.
- in addition to note down the exception in the logging message,
we also store it in a local variable, which it rethrown
before this function returns.

with this parameter, "backup" API can backup the given table, this
enables it to be a drop-in replacement of existing rclone API used by
scylla manager.
in this change:
* api/storage_service: add "table" parameter to "backup" API.
* snapshot_ctl: compose the full path of the snapshot directory in
`snapshot_ctl::start_backup`. since we have all the information
for composing the snapshot directory, and what the `backup_task_impl`
class is interested is but the snapshot directory, we just pass
the path to it instead the individual components of the directory.
* backup_task_impl: instead of scan the whole keyspace recursively,
only scan the specified snapshot directory.

Make the impl::is_abortable() return 'yes' and check the impl::_as in
the files listing loop. It's not real abort, since files listing loop is
expected to be fast and most of the time will be spent in s3::client
code reading data from disk and sending them to S3, but client doesn't
support aborting its requests. That's some work yet to be done.
Also add injection for future testing.

The method starts a task that uploads all files from the given
keyspace's snapshot to the requested endpoint/bucket. 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 (hint: it's good to have non-zero TTL value to
make sure fast backups don't finish before the caller manages to call
wait_task API).
If snapshot doesn't exist, nothing happens (FIXME, need to return back
an error in that case).
If endpoint is not configured locally, the API call resolves with
bad-request instantly.
Sstables components are scanned for all tables in the keyspace and are
uploaded into the /bucket/${cf_name}/${snapshot_name}/ path.
Task is not abortable (FIXME -- to be added) and doesn't really report
its progress other than running/done state (FIXME -- to be added too).
