Deployment: Convenient scripts or Makefile rules to deploy Lotus-based subnets

[adlrocha]

We should lower the barrier for users to be able to deploy new IPC subnets. We shouldn't expect users to know how to install and run Lotus to deploy a subnet. It would be easier for them to just provide them with a set of scripts that they can use to deploy their peers when they have created their new subnet. These scripts could also help us test and debug issues in the protocol.

High-level, these are some of the scripts we should provide in the agent:

• install-lotus: Install all of the dependencies needed to run sppacenet Lotus daemons.
• run-lotus-subnet <subnet-id>: Runs a Lotus daemon for a specific subnet.
