Proposed change to how config works

Description

Currently to use config - you set up a default configuration and you can run any of the binaries and it picks up that config and you can override it with the command line as well.

I think an extra thing that would make it more awesome is this:

instead of:

sushi config use --name=local_sushid
sushid
sushi config use --name=local_miner
sushim
sushi config use --name=local_wallet
sushi wt amount

it would be nice to just override the whole config:

sushid --config=local_sushid
sushim --config=local_miner
sushi wt amount --config=local_wallet

but still get to do this (which is generally useful shortcut for day to day):

sushi config use --config=remote_wallet1
sushi wt amount

I'm happy to make a PR that explores this
