Implement the functionality to translate the
`field IN (value1, value2,...)` expressions to proper Lucene queries
or painless script or local processors depending on the use case.
The `IN` expression can be used in SELECT, WHERE and HAVING clauses.
Closes: #32955
`CONVERT` works exactly like cast with slightly different syntax:
`CONVERT(<value>, <data_type)` as opposed to `CAST(<value> AS <data_type>)`
Moreover it support format of the MS-SQL data types `SQL_<type>`,
e.g.: `SQL_INTEGER`
