Default authenticate_with/authorize_with should be limited to localhost out the box.

Is your feature request related to a problem? Please describe.

Recently in the 3.0.0 branch when I do a full setup as in spinning up a new docker environment which calls rails webpacker:install in building the image fails because the database has not been setup. This im still trying to figure out, but to get around that i just commented out my entire config/initializers/rails_admin.rb and was able to build the docker image as normal. After deploying I forgot to un-comment out the config and the /admin was exposed to the world. Luckily I realized that shortly after and before any data was seeded.

Describe proposed solution(s)

If the config has not been specified to use a specific authenticate_with/authorize_with limit to only requests on local ip address.

Error from docker build

#3470 should have solved this. What's the commit hash of your RailsAdmin installation?
