Currently, commands that require multiple inputs from the user treat each input as an unrelated set of tasks. If the user realizes they made a mistake on an earlier input, their only choice is to cancel the next input (cancelling the command as a whole) and invoking the command again and start from scratch.
This change combines those inputs into a "wizard" (using the Azure UI library's wrapper on top of VS Code's more complex form of input/quick-pick prompts) that allow the user to go "back" to earlier prompts to verify/fix their entries/selections. Also adds a number of simple validations to try to keep the user along the happy path.
