Failure to publish blocks with /eth/v2/beacon/blocks

[mcdee]

POSTing block proposals to the /eth/v2/beacon/blocks returns an error. Simple reproduction (without proposal, but same error with them):

curl -X POST -H 'Content-type: application/json' --data '{}' http://localhost:9090/eth/v2/beacon/blocks
{"code":500,"message":"gossip broadcast_validation only supported"}

The same error occurs even if the broadcast_validation parameter is supplied.

curl -X POST -H 'Content-type: application/json' --data '{}' 'http://localhost:9090/eth/v2/beacon/blocks?broadcast_validation=gossip'
{"code":500,"message":"gossip broadcast_validation only supported"}

The first POST should work, given that gossip is the default value for broadcast_validation.
