Detailed description

This PR completes the following objectives broken down:

1. Creates a new folder for creating the pyroclastic package, this makes the seperation easier from general useful bash scripts.
2. A full replacement of all bash scripts with Python scripts, this has some interesting effects, such as:
   a) init_host.py will now store host.json in ~/.lava/host.json and will look for the file here unless overrridden by an environment variable.
   b) pyroclastic should be able to run fully dependent on what directories are specified in host.json.

Test plan

As I am only replacing the bash code, the CI/CD should pass without change
