Progress deadline exceeded not triggering a rollback during promotion

[macox]

Describe the bug

A canary that is almost completed and is copying the template spec to primary. The primary then exceeds its progress deadline as one of the pods isn't ready and a continual loop of exceeded its progress deadline logs are observed in Flagger, with seemingly no deadline. The status of the canary at this point is similar to:

Status:
  Canary Weight:  0
  Conditions:
    Message:               Canary analysis completed, starting primary rolling update.
    Reason:                Promoting
    Status:                Unknown
    Type:                  Promoted
  Failed Checks:           0
  Iterations:              0
  Phase:                   Promoting

To Reproduce

At the point that copying the template spec to primary is happening prevent one of the pods from starting correctly, this is likely to be easier if there is a number of pods.

Expected behavior

After progress deadline is exceeded I would expect a rollback to occur.
