Use stdout and local time for logging

[RichieB2B]

Structlog defaults to writing logs to stdout and writing timestamps in local time. IMHO initialise_logging() should not change these defaults.

It is very confusing when apps like orchestrator switch logging formats midway during initialisation.

import structlog
from nwastdlib.logging import initialise_logging

logger = structlog.get_logger(__name__)
logger.info("Goes to stdout with timestamp in local time")
initialise_logging()
logger.info("Goes to stderr with timestamp in UTC")
