Delete multiple JobExecution at once

**Description**  
Simpler way to delete multiple `JobExecution` than querying all, and removing every single objects fetched.

**Example**  
Add to the `Yokai\Batch\Storage\QueryableJobExecutionStorageInterface`, a method that:
- accept a `Yokai\Batch\Storage\Query` argument 
- delete `JobExecution` matched by the query
