POST /eth/v1/validator/register_validator

Give the beacon node access to the validators' registrations for the external builder network.

Gets the beacon node ready to communicate with outside builders. The beacon node needs to transmit the data to the builder network. In order to make sure the beacon node has accurate and timely registration information to give builders, it is anticipated that the validator client will send this information on a regular basis. Signing blinded beacon blocks that don't follow their most recent fee recipient and gas limit choices is not appropriate for the validator client.

Keep in mind that registrations for validators that are either pending or active need only be delivered to the builder network. It is necessary to filter out and avoid sending registrations for unidentified or terminated validators to the builder network.
