services: add ability to combine notary signers
Notes for witnesses: * [N sig + M multisig + K contract] combination is possible where N, M, K >=0. * Each verification script should be properly filled in. * Each invocation script should either be empty or contain exactly one signature.

We'll also use `NKeys` definition as the number of keys that participate in the

process of signature collection. This is the number of keys that could potentially
