Load environment vars logging

[ecanuto]

While we are loading environment vars, could be nice to have some logging messages but theres a problem, init_log is executes after load_env since we need to use "LOG_LEVEL" var. Maybe we can just stay without logging but will be nice to have a looks at this.

Some code for reference:

def load_env(filename=".env") -> None:
    if not os.path.isfile(filename):
        return

    logger.info(f"Loading environment vars from {filename}")
    try:
        stream = open(filename, "r")
        buffer = stream.readlines()
        stream.close()
    except Exception as e:
        logger.err(e)
        return
