Nautobot-server init should not make it so easy to overwrite the configuration.

Environment

• Python version: 3.8.9
• Nautobot version: 1.0.1

Steps to Reproduce

1. run nautobot-server init
2. run nautobot-server init again

Expected Behavior

Expected Nautobot to prevent me from overwriting my files, or at the very least create a backup before overwriting.

Observed Behavior

Nautobot does warn that the file exists, and asks if you want to overwrite, but if you select y, it will happily overwrite whatever you have. If there are encrypted settings in the database, then the data is now unrecoverable (unless you have stored the secret key somewhere).

I can take this one!
