feat(flake): refactor configuration definitions

Browse source 
Now a bunch of configurations may be created from two functions and a set:
    `pred` - a validator that says whether a configuration is valid
    `mkHost` - a generator for that system's configuration
    `machines` - a nested attrset containing all the info for the machines
