SQL: [docs] Add `beta[]` markup to all SQL pages (#36471) Closes: #36437

SQL: Implement IN(value1, value2, ...) expression. (#34581) 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

SQL: Implement null safe equality operator `<=>` (#35873) This operator handles nulls in different way than the normal `=`. If one of the operants is `null` and the other not it returns `false`. If both operants are `null` it returns `true`. Therefore in contrary to `=`, which returns `null` if at least one of the operants is `null`, this one never returns `null` as a result. Closes: #35871
