4fa07a1c8a tests/robustness: make merging histories work on []PersistedEvent 
Event histories after merging serve as an authorotative list of
events that can be seen as ones persisted by etcd, we don't need
PrevValue as part of it.

9aad6700d5 tests/robustness: add robustness test for watch with PrevKV() 
Kubernetes relies on the PrevKV() option in the watches it opens
against etcd. This commit adds a robustness test to validate the
same.

A watch response returned with PrevKV() is valid if:
The value in current event's prevKV matches the previous
event's value of the same key if this is not a create event.

There are cases where there can be a prevKV for a create event
as well, for example if a watch is opened after the key is creatd.
Since we don't simulate for that, we don't check for that.

Further, this adjusts revision numbers such that we can successfully create
a new replay. Needed now since we will have unit tests with
and without PrevKV co-existing and we requite creation of a
new replay everytime we validate PrevKV.

We also regenerate test data with so that prevKV exists in it

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.
