[BUG] Unable to create multiple x-events for a service

[krishin-js]

Describe the bug A clear and concise description of what the bug is.

To Reproduce Use-case, I need to trigger a task twice a day - one at 8am and other at 8pm. I've used the following:

x-events:
  TestTaskSchedule:
    Properties:
      Description: "EventRule to trigger the ECS Tasks"
      ScheduleExpression: "cron(0 8 * * ? *)"
      State: "ENABLED"    
    Services:
      - name: service1
        TaskCount: 2
        DeleteDefaultService: True 

  TestTaskSchedule2:
    Properties:
      Description: "EventRule to trigger the ECS Tasks"
      ScheduleExpression: "cron(0 20 * * ? *)"
      State: "ENABLED"    
    Services:
      - name: service1
        TaskCount: 2
        DeleteDefaultService: True 

I was getting the following error:

Traceback (most recent call last):
  File "/usr/local/bin/ecs-compose-x", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.9/site-packages/ecs_composex/cli.py", line 171, in main

  File "/usr/local/lib/python3.9/site-packages/ecs_composex/events/events_ecs.py", line 126, in define_service_targets
    service[0].template.add_resource(

    return self._update(self.resources, resource)
  File "/usr/local/lib/python3.9/site-packages/troposphere/__init__.py", line 658, in _update
    self.handle_duplicate_key(values.title)
  File "/usr/local/lib/python3.9/site-packages/troposphere/__init__.py", line 648, in handle_duplicate_key
    raise ValueError('duplicate key "%s" detected' % key)
ValueError: duplicate key "EventsAccessPolicy" detected

I have noticed that the Policy name is hard-coded to "EventsAccess". We may be able to resolve if we remove the hard-coding.

Expected behavior The cloud formation template should generate as expected with the event rules for the service.

Thanks @krishin-js I will take a look at that for 0.18 / main branch. Keep you posted.
