Surface the basic configuration with the user before proceeding with validation checking - Issue #196

[sambujangfofana]

Per #196,

@aaronphilip19 and I implemented this by defining the configuration file, data directory, csv file path, and the checkpoint based on user input and default values. We then prompted the user with a message through the command line interface asking them to review the basic configuration. If they answered yes, they would proceed with the validation; if they answered no, they had the option to change whatever they needed and to run the respective command (zamba predict or zamba train) through the terminal again.
