RemoteConfig failing if remote config file inherit from other config file

[matrixik]

Expected behavior

Two ideas (I have no preference):

1. Discard inheritance lines from remote configuration files
2. Try to load inherited file from same URL address
   So if file http://example.com/.rubocop.yml have inherit_from: .hound.yml try to load it from http://example.com/.hound.yml

Actual behavior

Started RuboCop with rubocop -d
