commit f7a37e6a, "Removing default injector anti-affinity rules",
disables anti-affinity for the injector pod. This is sufficient for
future application updates. However, during application-update an old
pod that still has anti-affinity will still prevent scheduling of a new
pod. This is observed on AIO-SX when testing application-update in
preparation for USM.
Using injector.strategy.rollingUpdate.maxUnavailable
(DeploymentStrategy) set to 100% the old pod will immediately terminate
while the new pod waits for its termination.
This is the workaround described in the original in starlingx bug:

Test Plan:
PASS AIO-SX vault sanity
PASS application-update
