Set drone address to always be the initial network entry point (#1847)

* Set drone address to always be the initial network entry point, so that even when leaders rotate the client can still find the drone

* Extract drone address as a separate argument to bench-tps

* Add drone port to client.sh instead of setting it in bench-tps

* Add drone entrypoint to scripts

* Fix build error
