Added `add_async_runtime` method for appending corutines, wrapped in `asyncio.run()`
Example:
python
class TestAsyncRuntime:
"""
Class must implement `run` method
"""
async def _test_async_runtime(self):
while True:
print(random.random())
await asyncio.sleep(1)
def run(self):
asyncio.run(self._test_async_runtime())
app.add_async_runtime("test_async", runtime=TestAsyncRuntime())
