feat(sender): support web3signer

[NazariiDenha]

Purpose or design rationale of this PR

Instead of storing a private key in config.json (major risk of leaking secrets), we initialize a secure wallet(web3signer) as a standalone service. rollup-relayer will then send signing requests to this service.

This PR adds desired functionality into rollup-relayer, specifically to sender

Currently web3signer doesn't support BlobTx, so CommitSender still need sign txs ad before. Changed configuration relayer, so now type of signing may be changed (PrivateKey or RemoteSigner)
