Lars Maier 12eebb15fe Feature/new server infra (#7733) 
* Decoupled IO handling from Scheduler.

* Fixed SSL start up bug.

* Replaced Scheduler with new worker farm implementation.

* Added minimal statistics and info string for Scheduler.

* Added support for timed submissions.

* Updated delayed submission api. Updated code that used timers.

* Extracted new Scheduler into a virtual parent class. The implementation can now depend on the usecase.

* Signal handler now working.

* Changed threads names, `_stop` is atomic, check for failure during thread start + exception handling like old scheduler did.

* Commented on source code and added TODOs.

* Played around with start-stop-conditions

* Play around with start stop condition.

* start stop cond

* Sart Stop Conditions

* Removed bad cv_status check.

* Bug fix: now compare the actual objects instead of pointer values. Setup t1 and t2 depending on the thread id.

* Moved most of the stuff now unrelated to the Scheduler to GeneralServer. Got rid of JobGuard.

* Instead of waiting for a thread to terminate, put it on a clean up list and check for its termination in each supervisor run.

* Allow detaching long running threads.

* Fixed test mock.

* Updated the WorkHandle logic. Removed post functions.

* Fixed crash when obtaining shared_ptr from this in destructor.

* Added lost mutex.

* Fixed memory leak.

* Fixed merge bug.

* Changed a lot of code to optimize the scheduler.

* Fixed bug of invalidated iterator. Dont remove task on shutdown at different places. Let scheduler threads run until queue is empty.

* Only by value calls to queue.

* Added options again.

* Clean up of code.

* UI Request Lane added.

* Bug fixes in Scheduler.

* Applied reformat.

* Use sigaction.
