This PR marks actions as PENDING while they are being executed. Out of this we can remove the dependency on a long-lived database transaction that can time out and fail while execution may have succeeded.
This attempts to address a couple of issues that have shown up lately:
The behavior I've opted for here is: success and failures during execution result in the same behavior as before, however if there is an exception during execution, (such as from interacting with graph-node or from the contracts), then the Action is returned to APPROVED state and will be processed again on the next execution batch.
One edge case this introduces is that if the process were to be interrupted while Actions are marked PENDING, then those will be left in that state. A warning is issued to the operator that these will need to be examined and cleared manually.
