TODO: create rspec tests for GeneralJob (or later called ProvisioningJob)

[oveits]

to be tested (minimum): GeneralJob.perform_now(object, "mymethod")

• Provisioning Task created? Correct attributes (model and view) for
  • method returning true or false
  • aborting method GeneralJob.perform_later(object, "mymethod")
• Provisioning Task created? Correct attributes (model and view) for
  • method returning true or false
  • aborting method
• Delayed Job created? Attributes updated correctly?
• Delayed Job executed? Attributes updated correctly? GeneralJob.cancel(object, "mymethod")
• expect to return true if invoked directly after perform_later
• expect to return false if invoked long enough after perform_later (longer than the execution of mymethod takes
