URL: https://github.com/apache/pinot/pull/12532
inspired by JSONEXTRACTINDEX, allows extracting contexual json array
elements matching a given json match predicate, using the json index
eg:
For a dataset like
```
{"jsonDoc": [{"name__s": "key00", "value": 1}, {"name__s": "key01", "value":
2}, {"name__s": "key02", "value": 3}, {"name__s": "key03", "value": 4}]}
{"jsonDoc": [{"name__s": "key10", "value": 5}, {"name__s": "key11", "value":
6}, {"name__s": "key12", "value": 7}, {"name__s": "key13", "value": 8}]}
{"jsonDoc": [{"name__s": "key20", "value": 9}, {"name__s": "key21", "value":
10}, {"name__s": "key22", "value": 11}, {"name__s": "key23", "value": 12}]}
{"jsonDoc": [{"name__s": "key30", "value": 13}, {"name__s": "key31",
"value": 14}, {"name__s": "key32", "value": 15}, {"name__s": "key33", "value":
16}]}
{"jsonDoc": [{"name__s": "key40", "value": 17}, {"name__s": "key41",
"value": 18}, {"name__s": "key42", "value": 19}, {"name__s": "key43", "value":
20}]}
```
```
select $docId, jsonextractarrayindex(jsonDoc, '$..value', 'INT_ARRAY', 0,
'REGEXP_LIKE("$..name__s", ''key.2'')') from jsonArrayExtractTest limit 10
```
returns
```
[{"name__s":"key00","value":1},{"name__s":"key01","value":2},{"name__s":"key02","value":3},{"name__s":"key03","value":4}]
1
[{"name__s":"key10","value":5},{"name__s":"key11","value":6},{"name__s":"key12","value":7},{"name__s":"key13","value":8}]
5
[{"name__s":"key20","value":9},{"name__s":"key21","value":10},{"name__s":"key22","value":11},{"name__s":"key23","value":12}]
9
[{"name__s":"key30","value":13},{"name__s":"key31","value":14},{"name__s":"key32","value":15},{"name__s":"key33","value":16}]
13
[{"name__s":"key40","value":17},{"name__s":"key41","value":18},{"name__s":"key42","value":19},{"name__s":"key43","value":20}]
17
[{"name__s":"key00","value":1},{"name__s":"key01","value":2},{"name__s":"key02","value":3},{"name__s":"key03","value":4}]
1
[{"name__s":"key10","value":5},{"name__s":"key11","value":6},{"name__s":"key12","value":7},{"name__s":"key13","value":8}]
5
[{"name__s":"key20","value":9},{"name__s":"key21","value":10},{"name__s":"key22","value":11},{"name__s":"key23","value":12}]
9
[{"name__s":"key30","value":13},{"name__s":"key31","value":14},{"name__s":"key32","value":15},{"name__s":"key33","value":16}]
13
[{"name__s":"key40","value":17},{"name__s":"key41","value":18},{"name__s":"key42","value":19},{"name__s":"key43","value":20}]
17
```
i.e. extracts the corresponding array element(s) where a certain json
condition is met. Also adds a way to solve REGEXP_LIKE on JSON_MATCH
