Remove vllm.logger.init_logger dependency

[kzawora-intel]

vLLM APIs change, as experienced in #52, and when they do, users might experience crashes on upstream. To avoid possible future import errors, we should import as little as possible from vLLM. Considering that current vLLM init_logger method looks as follows:

def init_logger(name: str) -> Logger:
    """The main purpose of this function is to ensure that loggers are
    retrieved in such a way that we can be sure the root vllm logger has
    already been configured."""

    return logging.getLogger(name)

There isn't really any reason not to interact with logging directly.
