1a8437f2c9 Add ability to ignore unknown keys in JSON object for named tuples 
This can be useful in case your input JSON is complex, while you need
only few fields in it.

This behaviour is controlled by the
input_format_json_ignore_unknown_keys_in_named_tuple setting name, that
is turned OFF by default.

This will, almost, allow to parse gharchive dataset without jq. "almost"
because of two things:
- Tuple cannot be Nullable, so such keys with Tuple type in ClickHouse
  cannot be `null` in JSON
- You cannot use dot.dot notation to extract columns for file() engine,
  only tupleElement()

Untangle query result cache settings 
This PR modularizes the configuration options of the query result cache
(QRC).

1. Add a feature toggle "allow_experimental_query_result_cache = false"
   which controls whether the experimental QRC can be used at all. This
   configuration option will be removed once the QRC becomes
   non-experimental.

2. Modularize the existing two configuration settings
   "enable_experimental_query_result_cache" and
   "enable_experimental_query_result_cache_passive_usage" into three
   orthogonal settings:

   - "use_query_result_cache = false" controls whether a query (or all
     queries of the session) utilize the query result cache

   - settings "use_query_result_cache_passive_usage = true" and
     "use_query_result_cache_active_usage = true" control the way a
     query (or all queries of the session) utilize the query result
     cache: "passive" use is reading, "active" use is writing.

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
