Rails: security cop which finds potential places with SQL injection

[roman-dubrovsky]

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

I'd like to have a cop which will help me to find unsecured places where we can apply SQL Injection. This cop can already exist. If not, I think we can suggest it for the rubocop-rails gem.

Additional context.

I am not sure that any of existing security cops is about SQL injections. There are cop about eval, json load, yml load, marshal load and files open. https://github.com/rubocop-hq/rubocop/tree/master/lib/rubocop/cop/security

Looks like we need custom cop
