Wind Tunnel scenario packaging

[ThetaSinner]

To deploy Wind Tunnel scenarios, a mechanism is needed to package them. The target environment is really any distributed compute environment but for now, we'll focus on NixOS machines and assume that they do not have the resources to build scenarios from scratch.

For context, each Wind Tunnel scenario is a binary which needs to be run on 1 or more machine. It may optionally have 1 or more happs that need to be built and provided with the scenario.

Either this needs to be bundled in a way that can be unpacked and run on a NixOS machine, or it needs to be possible to a partial build of the Wind Tunnel project that only builds the scenario and happs that are needed.

Best estimate for this issue is 3 days.
