This PR removes the existing Operator documentation pages from the core ScyllaDB docs. I have:
- removed the Operator page and replaced it with the link to the Operator documentation.
- created a redirect.
- updated the links to the Operator.
Closes#11154

This pull request introduces a "synchronous mode" for global views. In this mode, all view updates are applied synchronously as if the view was local.
Marking view as a synchronous one can be done using `CREATE MATERIALIZED VIEW` and `ALTER MATERIALIZED VIEW`. E.g.:
```cql
ALTER MATERIALIZED VIEW ks.v WITH synchronous_updates = true;
```
Marking view as a synchronous one was done using tags (originally used by alternator). No big modifications in the view's code were needed.

In issue #10966, a user noticed that Alternator writes may be reordered
(a later write to an item is ignored with the earlier write to the same
item "winning") if Scylla nodes do not have synchronized time and if
always_use_lwt write isolation mode is not used.
In this patch I add to docs/alternator/compatibility.md a section about
this issue, what causes it, and how to solve or at least mitigate it.
Fixes#10966

This PR extends #9209. It consists of 2 main points:
To enable parallelization of user-defined aggregates, reduction function was added to UDA definition. Reduction function is optional and it has to be scalar function that takes 2 arguments with type of UDA's state and returns UDA's state
All currently implemented native aggregates got their reducible counterpart, which return their state as final result, so it can be reduced with other result. Hence all native aggregates can now be distributed.
Local 3-node cluster made with current master. `node1` updated to this branch. Accessing node with `ccm <node-name> cqlsh`
I've tested belowed things from both old and new node:
- creating UDA with reduce function - not allowed
- selecting count(*) - distributed
- selecting other aggregate function - not distributed
