worker: make windows workers daemons

The windows workers weren't daemons and were not correctly killed when ctrl-c'd from the terminal. Withi this change when the main thread is killed, all daemons get killed as well.
I also reduced the time we give to workers to cleanup nicely to not have people ctrl-c'ing when they get inpatient.

The output when threads clened up nicely:
  PS C:\<dir>> hg.exe sparse --disable-profile SparseProfiles/<profile>.sparse
  interrupted!
The output when threads don't clenup in 1 sec:
  PS C:\<dir> hg.exe sparse --enable-profile SparseProfiles/<profile>.sparse
  failed to kill worker threads while handling an exception
  interrupted!
  Exception in thread Thread-4 (most likely raised during interpreter shutdown):
  PS C:\<dir>>

Test Plan:
Run hg command on windows (pull/update/sparse). Ctrl-C'd sparse --enable-profile command that was using threads and observed in proces explorer that all threads got killed.
ran tests on CentOS

Remove a file that was added via merge. Since the file is not in parent 1,
it should not be in the diff.
