This PR adds support to missing DSN in Lock component

```
framework:
  lock: sqlite:/tmp/db
  lock: mysql:host=localhost;dbname=test
  lock: zookeeper://localhost:2181
```

The PR also removes intermediate "internal" services `.lock_connection.*` in favor of factory `StoreFactory::createStore`. Which remove duplicate code.

This PR also deprecate unused services `lock.store.*` and  `lock.store.*.abstract`

[HttpFoundation][FrameworkBundle] allow configuring the session handler with a DSN

```yaml
framework:
    session:
        handler_id: 'redis://localhost'
        handler_id: '%env(REDIS_URL)%'
        handler_id: '%env(DATABASE_URL)%'
        handler_id: 'file://%kernel.project_dir%/var/sessions'
```

etc.

the database connection is not shared with the ORM (don't mess with transactions.)
redis/memcached connections are shared between cache and session.
(as a reminder, cache and ORM share the db connection: we're ok with trashing the cache on a rollback)

Lock-related changes are a follow up of #34043.
(fabbot failure is false positive)
