(cherry picked from commit 072542a5cc)
Bind variables in CQL have two formats: positional (?) where a variable is referred to by its relative position in the statement, and named (:var), where the user is expected to supply a name->value mapping.
In 19a6e69001 we identified the case where a named bind variable appears twice in a query, and collapsed it to a single entry in the statement metadata. Without this, a driver using the named variable syntax cannot disambiguate which variable is referred to.
However, it turns out that users can use the positional call form even with the named variable syntax, by using the positional API of the driver. To support this use case, we add a configuration variable to disable the same-variable detection.
Because the detection has to happen when the entire statement is visible, we have to supply the configuration to the parser. We call it the dialect and pass it from all callers. The alternative would be to add a pre-prepare call similar to fill_prepare_context that rewrites all expressions in a statement to deduplicate variables.
A unit test is added.

Bind variables in CQL have two formats: positional (`?`) where a
variable is referred to by its relative position in the statement,
and named (`:var`), where the user is expected to supply a
name->value mapping.
In 19a6e69001 we identified the case where a named bind variable
appears twice in a query, and collapsed it to a single entry in the
statement metadata. Without this, a driver using the named variable
syntax cannot disambiguate which variable is referred to.

for following reasons:
1. the ppa in question does not provide the build for the latest ubuntu's LTS release. it only builds for trusty, xenial, bionic and jammy. according to https://wiki.ubuntu.com/Releases, the latest LTS release is ubuntu noble at the time of writing.
2. the ppa in question does not provide the packages used in production. it does provides the package for *building* scylla
3. after we introduced the relocatable package, there is no need to provide extra user space dependencies apart from scylla packages.
so, in this change, we remove all references to enabling the Scylla/PPA repository.

(cherry picked from commit 55ed18db07)
Task manager's tasks stay in memory after they are finished.
Moreover, even if a child task is unregistered from task manager,
it is still alive since its parent keeps a foreign pointer to it. Also,
when a task has finished successfully there is no point in keeping
all of its descendants in memory.
The patch introduces folding of task manager's tasks. Whenever
a task which has a parent is finished it is unregistered from task
manager and foreign_ptr to it (kept in its parent) is replaced
with its status. Children's statuses of the task are dropped unless
they or one of their descendants failed. So for each operation we
keep a tree of tasks which contains:
- a root task and its direct children (status if they are finished, a task
otherwise);
- running tasks and their direct children (same as above);
- a statuses path from root to failed tasks.
/task_manager/wait_task/ does not unregister tasks anymore.

- [ ] ** Backport reason (please explain below if this patch should be backported or not) **
Requires backport to 6.0 as task number exploded with tablets.

execute ALTER KS from within topology coordinator.

- "Enabling Raft": The relevant information is moved to other sections. The irrelevant information
is removed. The section no longer exists.
- "Verifying that the Raft upgrade procedure finished successfully" - moved under Schema
(in the same document). I additionally removed the include saying that after you verify
that schema on Raft is enabled, you MUST enable topology changes on Raft (it is not mandatory;
also, it should be part of the upgrade guide, not the Raft document).
- Unnecessary or incorrect references to versions are removed.
