Fixing multiple problems with state machine in virtual media

- Previously machine did not handle AnyEvent correctly,
  implementation in BaseState was always run
- Changing from ActiveState to ReadyState was bugged,
  previously only one of event SubprocessStopped or UdevNotification
  caused state change when it is required to wait for both
- Introduced longer timer when waiting for ReadyState during Eject and
  ActiveState during Inject, because ndbkit can timeout during Eject and
  it is required to complete before next inject can success.
- Added event notification when process is terminated
- Added resourcess classes to handle deletion and notifications
