Use threadpool for subscription checking (#465)

e-pettersson-ericsson · m-linner-ericsson · Christoffer-Cortes · web-flow · commit 5435c7b00da5 · 2020-06-12T14:15:18.000+02:00
- Add thread pool for SubscriptionHandler
- Setup threadpool settings for SubscriptionHandler in SpringAsyncConfig
- Add new properties for subscription handler thread pool
  with same values as event handler thread pool
- Update test and info to use new properties
- Set org.mongodb.driver.protocol.command log out to error
- Fix of docker-compose correct path to rules
- Add config for subscription handler execution pool in tests
* Step patch version to 2.0.1
* Update default values to match eventhandler threadpool
