Add script to generate missing async tests using CST transformations

[Copilot]

Description

Implements compelete_missing_test_for_queue.py script to automatically generate async test versions from sync tests in test_queue.py, following the CST-based pattern established by compelete_missing_async_methods.py.

Changes

• scripts/compelete_missing_test_for_queue.py: Main script that parses test functions, identifies missing async versions (45 tests), generates them with proper transformations, and formats output

• scripts/scripts_utils/test_ast.py: CST utilities for test transformations

  • AsyncTestTransformer: Converts pgmq.method() → await pgmq.method_async() and time.sleep() → await asyncio.sleep()
  • FillMissingTestsToModule: Inserts async tests after sync counterparts and adds asyncio import

• scripts/scripts_utils/config.py: Added test file path constants

Example transformation

# Input (sync test)
def test_send_and_read_msg(pgmq_setup_teardown):
    pgmq, queue_name = pgmq_setup_teardown
    msg_id = pgmq.send(queue_name, msg)
    time.sleep(1)
    msg_read = pgmq.read(queue_name)

# Output (generated async test)
async def test_send_and_read_msg_async(pgmq_setup_teardown):
    pgmq, queue_name = pgmq_setup_teardown
    msg_id = await pgmq.send_async(queue_name, msg)
    await asyncio.sleep(1)
    msg_read = await pgmq.read_async(queue_name)
