Fix instance errors (#34)

* Fix some common errors when starting up.

Added more polls for services that we want to make sure are up and running.

Fixed issue where launch script wouldn't run when /snap/bin wasn't in the PATH.

* Added very basic resiliance to launch.sh script.

Tears down a machine and attempts to rebuild it if the build drops into an error state.
