Add an ability to format info date and insert date expression into JDBC SQL queries

## Background
Users want to customize SQL queries with information date based dates as part of an expression, including table names.
For example:
```
SELECT * FROM my_table_202402
```
where `202402` is `yyyyMM` part of the information date.

## Feature
Add an ability to format info date and insert date expression into JDBC SQL queries .

## Example
```hocon
input.sql = "SELECT * FROM my_table_${formatDate(beginOfMonth(@infoDate), 'yyyyMM)'}"
```

## Proposed Solution
1. Introduce `formatDate()` that can be used like this: `formatDate(@infoDate, 'yyyyMM)'` => `202402`
2. Allow date expressions in SQL queries, for example using `${}` escaping (see the example above).
