• run fides init and confirm that the flow works, as well as prompting about user analytics

Description Of Changes

The side-effect of having the fides.toml always be created whether it exists or not is a bit redundant and potentially error-prone (see the attached issue for more discussion). As such, the config file should only be created when a user specifically runs the fides init command

Due to this change though, we also needed to update how analytics_opt_out is handled, given that before we always expected the user to have a file-based configuration file to update. The behaviour is now that we assume analytics is false if there is no config file, but will prompt the user for it when they run fides init. This means we defaulting to opt-out and are no longer prompting the user every time they use the CLI to update this. I think this is no longer a major issue, as we should be relying more heavily on the user registration flow for valuable usage analytics.

@NevilleS can you take a look at the logic changes here and lmk if you're comfortable with these changes?

Particularly around only doing analytics opt-ins when someone runs fides init. My thinking here is that most of that heavy lifting should actually be done by user registration now

[ThomasLaPiana]

it looks like there is an error when running fides init and not choosing to opt-out of analytics

Tested in a local install of the branch and looks sharp! Added one question/comment earlier

Also, these are my favorite type of tongue twisters 😂
