[WIP] JSON predicate pushdown for Pinot

[robertzych]

Description

These changes allow the Trino-Pinot connector to perform predicate pushdowns for a combination of JSON functions.

For example, the following Trino function calls:

where
    contains(ARRAY['O'], json_extract_scalar(json, '$.orderstatus')) 
    AND (
      json_array_contains(json_extract(json, '$.stringArray'), 'O') 
      OR json_array_contains(json_extract(json, '$.stringArray'), 'F') 
    ) 
    AND (
        json_extract(json, '$.dne') IS NULL 
        OR json_array_contains(json_extract(json, '$.stringArray'), 'X') = false
        OR json_array_contains(json_extract(json, '$.intArray'), 0)
    );

Are translated to the following Pinot function calls:

where (
    JSON_MATCH(json, '"$.orderstatus" in (''O'')') 
    AND (
        JSON_MATCH(json, '"$.stringArray[*]" = ''O''') 
        OR JSON_MATCH(json, '"$.stringArray[*]" = ''F''')
    ) 
    AND (
        JSON_MATCH(json, '"$.dne" IS NULL') 
        OR JSON_MATCH(json, '"$.stringArray[*]" != ''X''') 
        OR JSON_MATCH(json, '"$.intArray[*]" = 0')
    )
)

The new session property (pinot.json_predicate_pushdown_enabled) defaults to false because JSON_MATCH can fail when a JSON index hasn't been configured in Pinot.

TODO: more tests
TODO: documentation for the supported JSON predicates and new session property

Additional context and related issues

PinotMetadata.applyFilter calls buildConstraintPQL which recursively walks through the call tree and returns the converted SQL if the entire call tree is supported.
