chore: adding k8s-update-strategy trait on marlowe-contract template (#…

…778)

This trait will introduce a change on `marlowe-contract` update
strategy, instead of create a new pod before terminating an old one
(Default policy, `RolloutUpdate`), it will terminate the old one before
creating a new one (`Recreate` strategy).

It is needed because with the default policy, the new pods are stuck in
`ContainerCreating` waiting for the EBS volume allocation.
