	val host = config.jdbcHost match {
	case Some(overrideHost) => overrideHost
	case None =>
	if (config.snowflakeRegion == "us-west-2")
	s"${config.account}.snowflakecomputing.com"
	else if (regionsWithoutAwsSubdomain.contains(config.snowflakeRegion))
	s"${config.account}.${config.snowflakeRegion}.snowflakecomputing.com"
	else
	s"${config.account}.${config.snowflakeRegion}.aws.snowflakecomputing.com"
	}

we check if regional endpoint doesn't contain aws part and add it to all regions otherwise.

For non-AWS regions we can end up west-europe.azure.aws.

Since #59 we can overwrite the host, but we can improve inference to use it less often.
