Make process state update asynchronous
Created originally on Bitbucket by cdevienne (Christophe de Vienne)
Currently the process state is updated in the same transaction as the corresponding logentry.
This simple fact make any node input/output update in the process block each others, making the whole server a lot more synchronous than expected.
We need to remove the process state update from the logentry insertion transactions, and have a dedicated micro-service for updating the process states.
