Use information from strategic merges to improve
the quality of diffs, particularly for list items
(order no longer important, and adding/removing an
item from a list just shows that item in the diff,
not the whole list)
Move wait logic out of raw and into common and use that
logic in scale
Fix a few broken wait condition cases highlighted by scaling
up and down
Move scale-related tests into dedicated test task file
Additional service related tests
Ensure that Deployments and Daemonsets properly await
all replicas to be available. Correctly handles the
subtle edge case when a service account no longer exists.

When the ansible k8s module is refreshing the tokens from the local kube
config, it should save those token to the kube config file.
If this is not done, this might break the next kube client call as the
token in the local kube config file is not valid anymore and refreshing
can fail.
This commit is adding an env var K8S_AUTH_PERSIST_CONFIG that can be
used to set this flag to true (default is false, same as current
behavior).
