Install pry-remote gem

What does this MR do?

This will allow us to debug our application without the need of changing the application server.

Usage:

binding.remote_pry

This will add a breakpoint similar to binding.pry which will stop the execution of your script. You can connect to this session with the following command from your terminal;

$ pry-remote

Note: I've already opened a PR to fix the problem on pry-byebug gem but we can keep using the version I have until the maintainers of that project decide to apply PR.
