Issue title: localnet docker image is sensitive to poor network conditions
 Issue body: I was using https://hub.docker.com/r/solanalabs/solana/ from a poor hotel wifi connection recently and it was unusable, the leader and/or drone was not starting correctly.

Need to replicate those conditions, perhaps find wifi with captive portal and don't login, and debug.

Could be a problem for hackathon/conference-like environments where wifi can be poor
