Implement API integration tests for Bursar Fee/fine scheduling feature

Overview:

API integration tests should be implemented for Bursar Fee/fines feature, particularly for scheduling.

Requirements/Scope:

• Karate tests should be implemented in separate folder - bursar-feefines-scheduling.
• Tests should cover positive business cases:

1. (precondition) create hourly based task-> verify execution after 1 hour
2. (precondition) create a couple of hourly based tasks-> verify execution of every task after 1 hour and with 1 hour between executions
3. (precondition) create daily based task-> verify execution at the time specified in Scheduled time
4. (precondition) create a couple of daily based tasks - verify executions of all tasks (if two or more tasks scheduled at the same time, they should be executed one after another)
5. (precondition) create a weekly based task -> verify execution at the time and day of week specified in Scheduled time
6. (precondition) create a couple of weekly based tasks - verify executions of all tasks (if two or more tasks scheduled at the same time, they should be executed one after another)

• Tests should cover negative business cases:

1. Select patron group where there are no active users (scheduling should fail in this case).

Acceptance criteria:**

• Both positive and negative cases are implemented
• Karate tests are passed on corresponding Jenkins job
