SNOW-1800528 don't log anything if logLevel is set to OFF

[sfc-gh-dszmolka]

Description

In #957 is was reported that even with
snowflake.configure({ logLevel: OFF });

which is expected to disable logging; a single logline is still logged

{"level":"INFO","message":"[2:27:54.321 PM]: Configuring logger with level: -1, filePath: undefined, additionalLogToConsole: undefined"}

at default INFO level before setting loglevel to -1 and actually disabling logging.

Moving this logline to after the logger has been configured with local loglevel allows for preserve the same information for the ones who need it for tracking purposes, and stop logging it for the ones who wish the driver to not emit logs.
