[OC-4782] add dev recipe for easy hacking on Chef Server core

This recipe will flip a Chef Server installation into development mode
for easy hacking on the underlying server components.

After this recipe has been applied git checkouts for all of Chef Server's
main software components will be available at `/opt/chef-server-dev/code`.
These component checkouts will also be fully symlinked into the underlying
Chef Server installation which means changes made to any component will
be reflected in the running Chef Server instance.
