wait - wait for a condition to become true

Wait provides one function: For.

	err := wait.For(func() (bool, error) {
		err := trySomething()
		if err != nil {
			if isFatal(err) {
				return false, err
			}
			return false, nil
		}
		return true, nil
	})

It calls its function argument over and over until:

• a timeout occurs (failure)
• the bool becomes true (success or failure depending on error)
• if ExitOnError(true) and the error becomes non nil (failure)
