[enhancement] In ord.yaml specifying options for subcommands

[GaloisField2718]

Hello,

I think about adding subfields into ord.yaml file for subcommands options'.

Maybe something like this:

wallet: {
    name: "MyWallet",
    no-sync: false
}

I don't know what should be modified from src to integrate such options, but it can simplify some commands.

Same with http-port from server subcommand.
If we run multiple instances it's easier to make one conf per instance.
