Evaluate move from argparse to click library

[tzarski0]

Problem Statement

There are certain limitations with the current argparse cli interface that makes it hard to track dependencies between variables. For example in deploy task if manager_ip = then manager_gateway and manager_mask is required, but when manager_ip = "pat:" then manager_gateway and manager_mask shouldn't be required, but tool still asks for it.

Proposed Solution

Evaluate move to click library to simplify the cli interface. For basic user, basic parameters would be given in cli interface. For power user, all parameters would be specified in the input yaml file (this will be developed later, but we need to make sure new cli will support this in the future).

Is this something we can solve with this move too? #42
