https://github.com/apache/incubator-brooklyn/pull/501
fix time-sensitive sensor derivation when rebinding to old sensors
before this, autoscaler might scale out on rebind, because the
last total reqs might be 100, if data is v old, current value might be
10000;
a recent timestamp is attached to initial value, meaning it computes 9900
new reqs in a 1s window.
this forces an invalid timestamp for enrichers
better fix would be to store timestamp on sensors themselves
