Rene Moser 8ec66713d9 cloudstack: fixes and improvements 
- cs_affinitygroup: add project support
  Project support in CloudStack for affinity groups is going to be fixed/implemented in the near future, this module should already support.

- cs_affinitygroup:  fix missing returns in doc

- cs_volume: fix disk offering not found

- cs_volume: fix volume not found if created with display_volume=no

- cs_firewall: argument zone is missing, default zone is always used.
  credits for reporting and fixing to @atsaki
  closes #1320

- cs_instance: fix user_data base64 encoding fails if not a string
