Customizable habitats

[Kampfkarren]

To get MockDataStoreService working with Lemur without monkey patching, RunService:IsServer() (at the time of writing, an unimplemented API) needs to return true. However, I'm not comfortable making RunService:IsServer() always return true on Lemur. I imagine there are many other cases like this.

Habitats should be easily customizable for arbitrary options for situations like this. In this case, there should be an easy way to tell Lemur "I want RunService:IsServer() to return true" without having to monkey patch.

Example: Without anything like this, I have to do this...

local RunService = game:GetService("RunService")
local runServiceIndex = getmetatable(RunService).__index

getmetatable(RunService).__index = function(self, key)
	if key == "IsServer" then
		return function() return true end
	end
	
	return runServiceIndex(self, key)
end

Do you think that this could be solved by the script scheduling work I've been working on in #93? Then, to make your tests run from a server-like environment, you'd make a Script, where RunService:IsServer() would return true.

Additionally, we could probably add a networking model argument to the habitat to set what sort of network should be emulated by default.

I like that solution for this case in particular, but this issue still stands for most other things.
