General purpose decision engine threadpool

Registered by Dantali0n on 2019-09-03

Watcher spends a large portion of time waiting for I/O operations such as writing to disc or waiting for responses to network requests. The time it takes to perform such operations can typically be reduced significantly by implementing parallelism. The general purpose threadpool for the decision engine will allow arbitrary methods to be executed in parallel. The amount of workers in the threadpool should be user configurable
