GetSpec() can be called concurrently in
manager/container.go.updateSpec()
results into a concurrent map access on the labels map because we're
directly updating the map inside GetSpec(). The labels map from the
container handler is not a copy of the map itself, just a reference,
that's why we're getting the concurrent map access.
Fix this by moving the label update with restartcount to the handler's
initialization method which is not called concurrently.
