r15456: Inspired by a short discussion with abartlet on IRC.

- create "async" parameter for smbtorture to categorise async tests
  potentially hard for windows servers
- create "num-async" parameter to specify the number of simultaneous
  async requests to be made
- move RPC-ASYNCBIND test from "dangerous" to "async" (I should probably
  do the same for many others async tests...)

It's an interesting way to determine resources availability on windows
servers...
