Start and Stop dependent service

The “client” application needs the “home” service to be running in the
test environment on a specified port (3000). This commit starts up the
“home” application before the “client” test suite runs and then stops
the “home” application after the “client” test suite finishes running.
Adds pry-remote

To debug when “home” application is started as a deamon process. Can
not use “binding.pry”.
