a110e0f022 Allow to ignore errors while pushing to MATERILIZED VIEW 
This can be useful in the following scenarious:

- you want to duplicate the data to another table and you don't care
  about the errors
- you want to duplicate system.*_log to another server, you are adding
  materialized view that will push to Distributed table, but you don't
  want to miss original blocks in the local system.*_log
- you want to push some data to a 3d party service, using i.e. URL
  engine.

Renaming: "Query Result Cache" --> "Query Cache" 
Reasons:

- The cache will at some point store intermediate results as opposed to
  only query results. We should change the terminology now without
  having to worry about backward compat.

- Equivalent caches in MySQL (1) and Starrocks (2) are called "query
  cache".

- The new name is ca. 13.8% more catchy.

(2) https://docs.starrocks.io/en-us/2.5/using_starrocks/query_cache

Deprecate Gorilla compression of non-float columns 
Reasons:

1. The original Gorilla paper proposed a compression schema for pairs of
   time stamps and double-precision FP values. ClickHouse's Gorilla
   codec only implements compression of the latter and it does not
   impose any data type restrictions.
   - Data types != Float* or (U)Int* (e.g. Decimal, Point etc.) are
     definitely not supposed to be used with Gorilla.
   - (U)Int* types are debatable. The paper only considers
     integers-stored-as-FP-values, a practical use case for which
     Gorilla works well. Standalone integers are not considered which
     makes them at least suspicious.

2. Achieve consistency with FPC, another specialized floating-point
   timeseries codec, which rejects non-float data.

3. On practical datasets, ZSTD is often "good enough" (**) so it should
   be okay to disincentive non-ZSTD codecs a little bit. If needed,
   Delta and DoubleDelta codecs are viable alternative for slowly
   changing (time-series-like) integer sequences.

Since on-prem and hosted users may still have Gorilla-compressed
non-float data, this combination is only deprecated for now. No warning
or error will be emitted. Users are encouraged to migrate
Gorilla-compressed non-float data to an alternative codec. It is planned
to treat Gorilla-compressed non-float columns as "suspicious" six months
after this commit (i.e. in v23.6). Even then, it will still be possible
to set "allow_suspicious_codecs = true" and read and write
Gorilla-compressed non-float data.

(*) Sec. 4.1.2, "Gorilla restricts the value element in its tuple to a
    double floating point type.", https://doi.org/10.14778/2824032.2824078

We can not update the select query 
An issue was opened as the select query was not updated after the alert of the view was executed, this is because the select gets ignored, the only way to change it is DROP/CREATE the view again.
So I want to add this information into our doc.

Implementation
* Fix for clang-today build fails - updated to use const in Context.cpp & const function in ActionsVisitior.cpp
* Updated to use QueryParameterVisitor to check if query has query parameters
* Updated executeTableFunction to check if table/table exists instead of try-catch approach
* Fixed small review comments and style comments.
Documentation:
* Addressed review comments and added the LIVE view part which was removed by mistake in the previous commits.

f801772a86 40907 Parameterized views as table functions 
Implementation:
* Updated parsers by adding a bool allow_query_parameters while creating ordinary view, which is used in interpreters to allow query parameters in SELECT.
* Added a check in ActionsVisitor if multiple parameters have same names while creating parameterised view.
* Added bool in StorageView to represent parameterized view.
* Updated processing of SELECT with parameter values to check for views and added substitution of values in the query parameters.

Testing:
* Added a test tests/queries/0_stateless/02428_parameterized_view.sql

Documentation:
* Updated the english documentation for VIEW.

The links at the very beginning of

don't work. They are reference other sections of the same document. This
is weird because there is a small index already on the right side. I
searched our documentation and this seems to be the only pages which do
so. Therefore removing the links altogether instead of fixing them.

chore: restore SYSTEM RELOAD MODEL(S) and moniting view SYSTEM.MODELS 
- This commit restores statements "SYSTEM RELOAD MODEL(S)" which provide
  a mechanism to update a model explicitly. It also saves potentially
  unnecessary reloads of a model from disk after it's initial load.

  To keep the complexity low, the semantics of "SYSTEM RELOAD MODEL(S)
  was changed from eager to lazy. This means that both statements
  previously immedately reloaded the specified/all models, whereas now
  the statements only trigger an unload and the first call to
  catboostEvaluate() does the actual load.

- Monitoring view SYSTEM.MODELS is also restored but with some obsolete
  fields removed. The view was not documented in the past and for now it
  remains undocumented. The commit is thus not considered a breach of
  ClickHouse's public interface.

chore: delete obsolete modelEvaluate() function + SYSTEM.MODELS view 
- The deleted function modelEvaluate() was superseded by
  catboostEvaluate().

- Also delete the external model repository, as modelEvaluate() was it's
  last user. Additionally remove the system view SYSTEM.MODELS for
  inspecting the repository.

- SYSTEM RELOAD MODELS is also obsolete. HOWEVER, it was retained and
  made a no-op instead of deleted.

  Why?
  The reason is that RBAC in distributed setups works by storing
  privileges (granted and revoked) as plain SQL statements in Keeper.
  Nodes read these statements at startup and parse them. If a privilege
  for SYSTEM RELOAD MODELS exists but parser doesn't recognize it
  nodes would fail to come up.

  Considered but rejected alternatives:
  - Ignore SYSTEM RELOAD MODELS during parsing RBAC privileges and
    return an error for regular SYSTEM RELOAD MODELS SQL. Special-case
    of no-op behavior, too brittle.
  - Remove SYSTEM RELOAD MODELS manually from Keeper via command-line
    manipulation of Keeper nodes or via SQL by dropping the privileges.
    Needs user intervention during upgrade.

Implementation:
- Added a bool to ASTQueryWithOutput & patched the usage in ClientBase.
- Added a new buffer TeeWriteBuffer which extends from WriteBufferFromFile (used to write data to the file) and has WriteBufferFromFileDescriptor (used to write data to stdout). The WriteBufferFromFileDescriptor uses the same buffer as TeeWriteBuffer.
- Added a new bool select_into_outfile_and_stdout in ClientBase to enable/disable progress rendering.

Testing:
 - Added a test tests/queries/0_stateless/02346_into_outfile_and_stdout.sh

Documentation:
- Updated the english documentation for the new option in SELECT.

01e1c5345a Add separate CLUSTER grant 
In case you have different roles for the same user on multiple clusters,
ON CLUSTER query can help to overcome some limitations.

Consider the following example:
- cluster_with_data, dev_user (readonly=2)
- stage_cluster, dev_user (readonly=0)

So when you will execute the following query from stage_cluster, it will
be successfully executed, since ON CLUSTER queries has different system
profile:

    DROP DATABASE default ON CLUSTER cluster_with_data

This is not 100% safe, but at least something.

Note, that right now only ON CLUSTER query it self is supported, but
separate clusters are not (i.e. GRANT CLUSTER some_cluster_name TO
default), since right now grants sticked to database+.

v2: on_cluster_queries_require_cluster_grant
v3: fix test and process flags as bit mask
