Option to turn off writing responds into filesystem

[KhyzhniakAlex]

As documentation says "Sometimes it is more convenient to set mocks right in tests, without storing them to the file system". But all other requests are unnecessary and written into filesystem.
I propose adding an option to turn off responds writing. It will give an ability to work only with interceptors and won't create redundant additional folder.

Interesting! Teremock initially was created as a file-based mocker, but your case is pretty valid, will do that.
