Async task handling improvement (#209)

* All threads are core thread

* Drop later submitted pathfinding tasks if task before is not started yet

* Auto-resize is gone

* Refine error handling

* Handle rejected execution

* Limit size and schedule on EntityScheduler

* Allow pr to build

* Remove duplicate path handling
Since it's a very rare case and Kaiiju has already done something to handle this

* Update thread and logger name format

* Core pool to 1

* Revert entity scheduler changes

* Expose queue size to config

* Add reject policy config to pathfinding

* [ci/skip] To uppercase

* [ci/skip] Add co-authors
