519617cfd0 tests/robustness: Tune Kubernetes tests to reduce number of delete requests 
Having too many delete requests is bad as they are not unique requests, so
linearization is more prone to timeout on them.

96987d8b5e tests/robustness: Implement stale reads without validation 
For now we just validate stale read revision, but not response content.
Reason is that etcd model only stores latest version of keys, and no
history like real etcd.

Validating stale read contents needs to be done outside of model
as storing whole history is just to costly for linearization validation.

ea3255b477 tests/robustness: Limit model to start only from fresh state 
It is just to complicated to support starting from non-empty etcd.
Existing implementation was very naive to assume that we can build
full state from just one request. We might consider implementing
validation of non-empty history in future, but for now settting
this limit should clean up the code and speed up development.
