This PR removes information about outdated versions, including disclaimers and information when a given feature was added.
Now that the documentation is versioned, information about outdated versions is unnecessary (and makes the docs harder to read).

Set filesystem permissions for the maintenance socket to 660 (previously it was 755) to allow a scyllaadm's group to connect.
Split the logic of creating sockets into two separate functions, one for each case: when it is a regular cql controller or used by maintenance_socket.
Fixes https://github.com/scylladb/scylladb/issues/16487.

* github.com:scylladb/scylladb:
maintenance_socket: add option to set owning group
transport/controller: get rid of magic number for socket path's maximal length
transport/controller: set unix_domain_socket_permissions for maintenance_socket
transport/controller: pass unix_domain_socket_permissions to generic_server::listen
transport/controller: split configuring sockets into separate functions
Option `maintenance-socket-group` sets the owning group of the maintenance socket.
If not set, the group will be the same as the user running the scylla node.
Add empty line before list of different checksums in
validate-checksums's description. Otherwise the list is not rendered.

It enables interaction with the node through CQL protocol without authentication. It gives full-permission access.
The maintenance socket is available by Unix domain socket with file permissions `755`, thus it is not accessible from outside of the node and from other POSIX groups on the node.
It is created before the node joins the cluster.
To set up the maintenance socket, use the `maintenance-socket` option when starting the node.
* If set to `ignore` maintenance socket will not be created.
* If set to `workdir` maintenance socket will be created in `<node's workdir>/cql.m`.
* Otherwise maintenance socket will be created in the specified path.
The default value is `ignore`.
* With python driver
```python
from cassandra.cluster import Cluster
from cassandra.connection import UnixSocketEndPoint
from cassandra.policies import HostFilterPolicy, RoundRobinPolicy
socket = "<node's workdir>/cql.m"
cluster = Cluster([UnixSocketEndPoint(socket)],
# Driver tries to connect to other nodes in the cluster, so we need to filter them out.
load_balancing_policy=HostFilterPolicy(RoundRobinPolicy(), lambda h: h.address == socket))
session = cluster.connect()
```
Merge note: apparently cqlsh does not support unix domain sockets; it
will have to be fixed in a follow-up.

when migrating to the uuid-based identifiers, the mapping from the
integer-based generation to the shard-id is preserved. we used to have
"gen % smp_count" for calculating the shard which is responsible to host
a given sstable. despite that this is not a documented behavior, this is
handy when we try to correlate an sstable to a shard, typically when
looking at a performance issue.
in this change, a new subcommand is added to expose the connection
between the sstable and its "owner" shards.

Currently, scylla.yaml is read conditionally, if either the user
provided `--scylla-yaml-file` command line parameter, or if deducing the
data dir location from the sstable path failed.
We want the scylla.yaml file to be always read, so that when working
with encrypted file (enterprise), scylla-sstable can pick up the
configuration for the encryption.
This patch makes scylla-sstable always attempt to read the scylla-yaml
file, whether the user provided a location for it or not. When not, the
default location is used (also considering the `SCYLLA_CONF` and
`SCYLLA_HOME` environment variables.
Failing to find the scylla.yaml file is not considered an error. The
rational is that the user will discover this if they attempt to do an
operation that requires this anyway.
There is a debug-level log about whether it was successfully read or
not.

instead of printing the result of the "validate" subcommand in a
free-style plain text, let's print it using JSON. for two reasons:
1. it is simpler to consume the output with other tools and tests.
2. more consistent with other commands.

This commit fixes mulitple links that were broken
after the documentation is published (but not in
the preview) due to incorrect syntax.
I've fixed the syntax to use the :docs: and :ref:
directive for pages and sections, respectively.

Now that the documentation is versioned, we can remove
the .. versionadded:: and .. versionchanged:: information
(especially that the latter is hard to maintain and now
outdated), as well as the outdated information about
experimental features in very old releases.
This commit removes that information and nothing else.
Closes#13680
The above file contained a paragraph explaining the limitations of
`scylla-sstable.rst` w.r.t. automatically finding the schema. This no
longer applies so remove it.
This reverts commit 32fff17e19, reversing
changes made to 164afe14ad.
This series proved to be problematic, the new test introduced by it
failing quite often. Revert it until the problems are tracked down and
fixed.
Loads the script from the specified path, then feeds the mutation
fragment stream to it. For now only Lua scripts are supported for the
simple reason that Lua is easy to write bindings for, it is simple and
lightweight and more importantly we already have Lua included in the
Scylla binary as it is used as the implementation language for UDF/UDA.
We might consider WASM support in the future, but for now we don't have
any language support in WASM available.
The inline-help of operations will only contain a short summary of the
operation and the link to the online documentation.
The move is not a straightforward copy-paste. First and foremost because
we move from simple markdown to RST. Informal references are also
replaced with proper RST links. Some small edits were also done on the
texts.
The intent is the following:
* the inline help serves as a quick reference for what the operation
does and what flags it has;
* the online documentation serves as the full reference manual,
explaining all details;
Provides a link to the architecture/sstable page for more details on the
sstable format itself. It also describes the mutation-fragment stream,
the parts of it that is relevant to the sstable operations.
The purpose of this section is to provide a target for links that want to
point to a common explanation on the topic. In particular, we will soon
move the detailed documentation of the scylla-sstable operations into
this file and we want to have a common explanation of the mutation
fragment stream that these operations can point to.
In both files, the section hierarchy is as follows:
Usage
Syntax
Sections with actual content
This scheme uses up 3 levels of hierarchy, leaving not much room to
expand the sections with actual content with subsections of their own.
Remove the Syntax level altogether, directly embedding the sections with
content under the Usage section.
Takes human readable values and converts them to serialized hex encoded
format. Only regular atomic types are supported for now, no
collection/UDT/tuple support, not even in frozen form.
Soon we will have a serialize operation. Rename the current print
operation to deserialize in preparation to that. We want the two
operations (serialize and deserialize) to reflect their relation in
their names too.
