vdk-core: support multiple ingesters from different types to be used with job_input

[duyguHsnHsn]

Currently, send_tabular_data_for_ingestion and send_object_for_ingestion in job_input only work with the default ingestion database that is set, instead of this we should support them to work with all the registered databases in

versatile-data-kit/projects/vdk-core/src/vdk/internal/builtin_plugins/ingestion/ingester_router.py

Line 32 in cd92087

class IngesterRouter(IIngesterRegistry, IIngester):

Their interfaces should look like this:

def run(job_input):
         .......
        job_input.send_object_for_ingestion(
                         payload=dict(id="Hello World!"), 
                         destination_table="hello_world", 
                         database="TRINO" 
                         )
         job_input.send_object_for_ingestion(
                          payload=dict(id="Hello World!"), 
                          destination_table="hello_world",
                          database="IMPALA"                        
                         )

For now, for each database type we can only have single ingester registered. Multiple connections from the same time will be implemented after #3222
