Add CREATE SCRIPT statements for deployment of the training UDF

[tkilias]

Background

• We need CREATE SCRIPT statements for all UDF and LUA Scripts
• For Lua we already have, see https://github.com/exasol/sagemaker-extension/blob/main/scripts/create_statement_template.sql

• For the Python UDF we still need them

  • They will look similar as the udf_wrapper in the UDFMock tests, except without the mock functions
  • Example: Assuming the udf_wrapper in https://github.com/exasol/sagemaker-extension/blob/cf0b4150afa688d7a1d683fcb1b36a196ba634e7/tests/test_autopilot_training_udf_mock.py#L18

    
    def udf_wrapper():
    from exasol_udf_mock_python.udf_context import UDFContext
    from exasol_sagemaker_extension.autopilot_training_udf import AutopilotTrainingUDF

  def mocked_training_method(**kwargs): return "test_job_name"

  udf = AutopilotTrainingUDF(exa, training_method=mocked_training_method)

  def run(ctx: UDFContext): udf.run(ctx)

the CREATE STATEMENT would look like

CREATE PYTHON3 SET SCRIPT AutopilotTrainingUDF(model_name VARCHAR(23), ....)
EMITS (model_name VARCHAR(32)) AS
    from exasol_sagemaker_extension.autopilot_training_udf import AutopilotTrainingUDF

    udf = AutopilotTrainingUDF(exa)

    def run(ctx):
        udf.run(ctx)
/

Acceptance Criteria

• Create CREATE SCRIPT statement for AutopilotTrainingUDF and AutopilotTrainingStatusUDF
