Truncate doesn't work for RetryingTarantoolClient

[Artyom Dubinin]

There is a line that this is a temporary hack, but in order not to lose and forget, I will add a ticket for this problem

cartridge-springdata/src/main/java/org/springframework/data/tarantool/core/BaseTarantoolTemplate.java

Lines 187 to 200 in 5e06e8f

 @Override 
 public void truncate(String spaceName) { 
     //FIXME implement truncate in cartridge-driver and remove this temporary hack 
     if (tarantoolClient instanceof ProxyTarantoolClient) { 
         boolean result = executeSync(() -> tarantoolClient.callForSingleResult( 
                 "crud.truncate", 
                 Collections.singletonList(spaceName), Boolean.class)); 
         if (!result) { 
             throw new TarantoolSpaceOperationException("CRUD failed to truncate space " + spaceName); 
         } 
     } else { 
         throw new UnsupportedOperationException("Truncate operation is not supported in the driver yet"); 
     } 
 }

Since truncate was implemented we now can remove this clutch:
