Adds a "sstables" array member to manifest.json.
For each sstables, keep the following metadata:
id - a uuid for the sstable (the sstable identifier
if the use-sstable-identifier option was used, otherwise
the sstable uuid generation)
toc_name - the name of the TOC.txt file
data_size and index_size - in bytes
first_token and last_token - of the sstable first and last keys.

Add a table member to manifest.json with the keyspace_name,
table_name, table_id, tablets_type, and, for tablets-enabled tables, get
tablet_count on each shard and write the minimum to manifest.json.
For vnodes-based tables, tablet_count=0.
For now, `tablets_type` may be either `none` for vnodes tables, or
`powof2` for tablets tables. In the future, when we support arbitrary
tablt boundaries, this will be reflected here, and it is likely we
would backup the whole tablets map sperately to get all tablet boundaries.

Add metadata about the node: host_id, datacenter, and rack.
This enables dc- or rack- aware restore.
Today this information is "encoded" into the snapshot hierarchy
prefixes, but if all manifest files would be stored in a flat
directory, we'd need to encode that metadata in the object name,
but it'd be better for the manifest contents to be self descriptive.

Add metadata about the manifest itself:
A version and the manifest scope (currently "node",
but in the future, may also be "shard", or "tablet")

Validate the manifest.json format by loading it using rjson::parse
and then validate its contents to ensure it lists exactly the
SSTables present in the snapshot directory.

This reverts commit 1bb897c7ca, reversing
changes made to 954f2cbd2f. It makes
incompatible changes to the object storage configuration format, breaking
tests [1]. It's likely that it doesn't break any production configuration,
but we can't be sure.

Augments the object storage document with config options etc for
using GS instead of S3.
TODO: add proper gsutil command line examples for manual managing of
GCP storage.
This patch intends to give an overview of where, when and how we store
data in S3 and provide a quick set of commands
which help gain local access to the data in case there is a need for
manual intervention.
The patch also collects in the same place links/descriptions for all
formats we use in S3.

this commit moves the object storage configuration guide from the developer
documentation to the user-facing admin documentation. the change reflects
the increasing importance of object storage integration in user-facing
features.
in this change:
- move relevant content from `docs/dev/object_storage.md` to
`docs/operating-scylla/admin.rst`
- reformat the content from Markdown to reStructuredText (RST)
- reword and restructure the content to be more user-friendly
- add explanations and context suitable for a broader audience
this change makes the object storage configuration information more
accessible to Scylla administrators and end-users, supporting the adoption
of new features built on top of object storage integration.

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.

Currently the doc assumes that object storage can only be used to keep
sstables on it. It's going to change, restructure the doc to allow for
more usage scenarios.
Someone thought that they actually represent real keys (the 'EXAMPLE' in their name was not enough).
Converted them to be as clear as can be, example data.

* add language specifier for better readability of the document.

* add more specific comment on the AWS related settings
* explain that endpoint should match in the CREATE KEYSPACE
statement and the one defined by the YAML configuration.

we get the path object storage config like:
```c++

so, the default path should be $SCYLLA_CONF/object_storage.yaml.
