Adding Config Wizard script to facilitate initial configuration of AST, and added several improvements to Config Wizard to improve usability.

Any issues with this @clhain ?

Thanks for the contribution Jason, this is good and timely stuff. I'd been planning to add a make file with some additional helper commands similar to some of what you have here e.g. 'make config' (to run the config script), 'make start' plus some additional e.g. 'make support-logs', etc, etc.

Implementation specifics of make vs bash script aside, I guess my main concern is whether we want to encourage people to manage their deployment configurations (specifically the configuration files, not the commands to run the configurator or the stack - which are definitely useful) with an additional abstraction over the existing abstraction. I don't love the idea of encouraging people to re-run the whole script to change a single bigip parameter for instance - obviously that's not good for anything but the smallest deployments - e.g. labs (which maybe is the intent).

Obviously you guys are the ones handholding folks through this so you can make the call, but for my money I'd rather be directing people to the yaml files directly for edits from the jump, and then just some helper commands to make the config script execution and docker stuff more friendly.

If we do want to go this route, would need to see some documentation for how we want people to approach configs with this alternate option included.
