provide a way to use OpsGenie on-call schedule with round-robin or balanced workload method

Description:

Automation for Jira supports the 'round-robin' method to assign the tickets automatically, but it can't be used for 'on-call' schedules created in Opsgenie. This method is available only if you pick the users from a group, role or defined list.

Why is it important?
At this moment, the Automation rule only asks to pick a team whose on-call schedule will be checked to assign the ticket. Some customers have multiple users working in schedule and there should be a way to assign the tickets to them using the following approaches:

• Balanced workload
• Random
• Round-Robin
