Add interactivity to create2 command

[crazyrabbitLTC]

In testing zos create2 I noticed that the interactive commands don't always work.

 ✘ dennisonzeppelin@Dennisons-MBP  ~/Documents/create2  zos push
Compiling contracts with Truffle...

Compiling your contracts...
===========================

> Compiling ./contracts/Migrations.sol

? Select a network from the network list development
Validating contract Demo
Uploading Demo contract as Demo
Deploying logic contract for Demo
Created zos.dev-1556636315855.json
 dennisonzeppelin@Dennisons-MBP  ~/Documents/create2  zos create2 Demo --salt 12345
A network name must be provided to execute the requested action.
 ✘ dennisonzeppelin@Dennisons-MBP  ~/Documents/create2 

In this case zos push prompted me to select a network from a list, but zos create2 did not. I would expect the behavior to be uniform across commands that require a network.

Indeed, we haven't added interactivity to create2. I'll try to tackle this soon, thanks for bringing it up!
