Add glueby command line interface gluey-cli

[rantan]

It is hard to use glueby for small things like try issuing colored coin or creating timestamp tx because of setting up the wallet.
If we can start to use glueby just like one command line utility like below

 $ glueby-cli -rpchost=127.0.0.1 -rpcport=12381 -rpcuser=user -rpcpassword=password 
 glueby-cli:001:0> wallet = Glueby::Wallet.create
 glueby-cli:002:0> Glueby::Contract::Payment.transfer(sender: wallet, receiver_address: 'mqYT....', amount: 1_000_000)

There is some point that needs consideration.

1. What wallet adapter should we use? It means how we store wallets in disks.
2. Run Ruby files on the glueby-cli environment.
