This causes the "fair" scheduler to run it too often in the detriment of other generators.
The intention was to run it every 2 hours but the measurement unit for 7200 was not specified.
Add more logs, including showing a generator name, in order to troubleshoot this kind of issues easier in the future.

Generators are now ordered by rank in the priority queue.
The rank computation formula is:
- 100/(1+generated_task_count) for high priority tasks
- 10/(1+generated_task_count) for medium priority tasks
- 1/(1+generated_task_count) for low priority tasks
Note the ranks are used when comparing generators both with the same priority and with different priority.
So now we are:
- giving an opportunity to all generators with the same priority to take turns generating tasks
- giving roughly 1 low priority and 10 medium priority tasks the opportunity to run for every 100 high priority tasks running.
After a generator generates a task, the generators are reordered in the priority queue based on rank.

* fix(scheduler): data race when pushing new tasks
the problem here is that scheduler can be closed in two ways:
- canceling the context given as argument to scheduler.RunScheduler()
- running scheduler.Shutdown()
because of this shutdown can trigger a data race between calling scheduler.inShutdown()
and actually pushing tasks into the pool workers
solved that by keeping a quit channel and listening on both quit channel and ctx.Done()
and closing the worker chan and scheduler afterwards.

* refactor(scheduler): refactor into a single shutdown
before this we could stop scheduler either by closing the context
provided to RunScheduler(ctx) or by running Shutdown().
simplify things by getting rid of the external context in RunScheduler().
keep an internal context in the scheduler itself and pass it down to all tasks.

* fix: remove inline GC and set a default value of gc interval
- remove inline GC
- add a default value of GC interval
- run the GC periodically by default with the default value if no interval provided
- generate GC tasks with a random delay(0-30s) between
- add IsReady() method to scheduler.TaskGenerator interface
