Title: CLI-flags to make database:create and database:drop idempotent

Very simple:

```bash
app/console doctrine:database:create
app/console doctrine:database:create --if-not-exists # <-- just exists with 0
```
```bash
app/console doctrine:database:drop --force
app/console doctrine:database:drop --force --if-exists # <-- exists with 0
```
