Support multi tenant db hosts

[RamyHakam]

In this PR we will support Multi-tenant db hosts, which means that for each tenant you can have a completely different host and port,
Some notes regarding this feature

1. All tenant DBs should have the same Driver type, Cuz For now the tenant Sechma is shared between all tenants
2. If your tenants host on localhost but with different ports, it is better to use IP rather than localhost in your host
3. In docker you should use IP rather than localhost
4. You can use docker.host.internal as your host in your docker env
   But remember to add it as an extra host in your compose file

Hello @RamyHakam,

First, thank you for your incredible work on this bundle. It has been incredibly useful and greatly simplifies multi-tenancy in Symfony applications.

However, I am experiencing an issue related to the recent merge. Specifically, the changes require hardcoding db_username, db_password, and even pdo_driver in my TenantConfig class.

For more details, see TenantDbConfigTrait.php.

Would it be possible to revert from:

$tenantConnection = DriverManager::getConnection($dsnParser->parse($dbConfiguration->getDsnUrl()));

to

$tenantConnection = DriverManager::getConnection($dsnParser->parse($this->dbCredentials['db_url']));

in DbService.php?

This change would allow for more flexibility in managing database credentials and avoid hardcoding sensitive information in the TenantConfig class.
