What did you expect to see?

OpsGenie sender should allow user to provide an API endpoint which is used for notifications.
This is essential, if you're running against EU OpsGenie endpoint (OpsGenie has two instances - EU and non-EU).

What did you see instead?

https://github.com/moira-alert/moira/blob/master/senders/opsgenie/init.go#L39 - it should just include additional stanza when initializing the client with chosen api endpoint.
Also examples should mention ways to use different than default endpoint.
