5cd501c27aFix: cast downtime replica annotations (#63)
* Test scale up with downtime replicas annotation in deployment manifest
* Fix: cast downtime replica annotations
To avoid false conditions between integers and strings.
When setting arg downtime-replicas to 1, and setting annotation
downtime-replicas to 0 for a specific deployment, deployment was not
scaled-up to original replicas during uptime period.
This behaviour is caused when getting annotations as strings, and
comparing those values to integers, p.e.: `replicas ==
downtime_replicas` is false if types are different.
