relay should only process transactions, forward all other operations to the local node #16
Description
This requires the relay to parse the transaction using the same parser than the endpoint, in order to read the kind field.
It should be kind: transaction otherwise we just forward it to the local node.
It's probably good to switch to TezosParsedOperations everywhere, including in the transport between FBR and FBE.
