Opsgenie REST client

How to use?

First of initiate the client with GeniKey. E.g., in init

func init() {
	opsgenieclient.Initiate(opsgenieclient.Config{
		ApiKey: "<your api key>",
	})
}

Now as the client is created, we can create an alert

opg, _ := opsgenieclient.CreateInstance(ctx)
_ = opg.CreateAlert(request)
