Use BLSPublicKeys for the list of relays

[come-maiz]

According to the specification,

mev-boost is initialized with a list of (BLSPublicKey, RelayURI) pairs representing trusted relays.

But currently we are not using any keys.

mev-boost/cmd/mev-boost/main.go

Line 35 in 9912f48

_relayURLs := []string{}

Is this required for the 0.1 release? Or better for the next milestone?

Once we have the keys, we should verify the returned SignedMEVPayloadHeader signature matches the BLS key associated with the IP of the relay and has a matching payloadId.

• Now we have a relay url scheme: <scheme>://<bls_pubkey>@<host>: https://github.com/flashbots/mev-boost/blob/main/cmd/mev-boost/main.go#L83
• we need to verify the relay signature in the getHeader relay response: somewhere around https://github.com/flashbots/mev-boost/blob/main/server/service.go#L246

relevant: ethereum/builder-specs#23

lets resolve how to handle this type of thing in that issue and I can put it into the spec
