- Only schedule Threads. Ditch support for Policies deciding

if they want to schedule Threads or Processes altogether
- Move setter methods for last_acquisition/last_release from
DynamicSchedulable to DynamicThread
- Rewrite aforesaid methods, along with the respective getter
methods, into Dynamic(Thread|Process)
