Do not log 404 errors

[reenjii]

Hello,

I have a workflow where I try to get an OpsGenie alert by alias to check existence and close it if needed.
Whenever I get an alert that does not exist on OpsGenie, SDK logs an error-level message on API 404 error.
This creates many error-level logs on my application despite everything working as expected.

Here is the culprit: https://github.com/opsgenie/opsgenie-go-sdk-v2/blob/master/client/client.go#L475

I want to remove this log because it is not an actual API error, and leave it to the caller to decide to log this information.

Thanks
