JDBC URL should be part of the PostgresReplicationConnection functionality

# What
In order to make easier the creation of `replication` type of connections we created the class `PostgresReplicationConnection`.
We added a new a default value for JDBC URL when it has not been defined in the config in an attempt to facilitate the connection creation, but it doesn't work for SSL connections.

If you need to create a SSL Replication connection, you need to first call `getDatabaseConfig` function from a `JdbcDatabase` object (`database`):
```
JsonNode databaseConfig = database.getDatabaseConfig();
```

And then call the create function with that config:
```
final Connection connection = PostgresReplicationConnection.createConnection(databaseConfig)
```

# Solution
Use the config on the function `createConnection` in order to automatically generate the required parameters when creating the connection.
