Description
I'd like to propose a change to config behaviour. Currently if you set config.filters = false or config.allow_comments = false in your global AA config, you can no longer use those features:
activeadmin/lib/active_admin/filters/resource_extension.rb:62:in `add_filter': Can't remove a filter when filters are disabled. Enable filters with 'config.filters = true' (ActiveAdmin::Filters::Disabled)
I would like to be able to disable them but still have an option to add filters and comments where I want them.
Default filters became a common problem in our projects: when the data set grows association filters start to consume a lot of memory. I'd like to make config.filters = false a standard practice in my organisation. By default our admin pages wouldn't have any filters, we would add just the ones we want.
The similar situation is with AA comments, I don't want them on every model. I'd better have comments disabled by default but add them where I need to.
I can make a PR if I get a thumbs up.
