Pass param for pre-created socket to uvicorn

[fialhocoelho]

During the integration tests, the built image triggered the error below:

[rank0]:[W215 15:13:14.568778632 ProcessGroupNCCL.cpp:1496] Warning: WARNING: destroy_process_group() was not called before program exit, which can leak resources. For more info, please see https://pytorch.org/docs/stable/distributed.html#shutdown (function operator())

                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: serve_http() missing 1 required positional argument: 'sock'

The above exception was the direct cause of the following exception:

Looking for the function serve_http() in vllm/entrypoints/launcher.py, I found that a recent modification in PR #13113 (post vLLM v0.7.2) added an optional parameter sock to allow uvicorn to use a pre-created socket.

We actually use the serve_http() function in /src/vllm_tgis_adapter/http.py. Because of this, I added a parameter sock=None to maintain the same function signature we used before. I'm not sure if we need to use a pre-created socket for multi-GPU support or for something else.

@dtrifiro I will add your suggestion (editing the current commit) to keep the function backwards compatible with 0.7.2 ASAP

Thanks @fialhocoelho, I'm moving this over to #233
