[CORE FEATURE] Implement a safe execution environment for external Lua code

Is your feature request related to a problem? Please describe.

LAMENT happens to boil down to a sandboxed Lua execution environment for its configuration and recalibration architecture. The declarative configuration is stored as Lua code under specific locations (src/lament/loader.lua @ Line 27) that can also be configured with lament's self config file. How the declarative configuration will be executed and converted into actual configuration files is specified via backends, which are basically plugins for LAMENT, that have restricted, proxied and supervised access to the io, os, lfs and lpeg APIs. In addition, these backends define how existing configuration files will be used to create the declarative configuration scripts again.

The first problem we have is that we have never demonstrated if we can safely load external Lua code and execute it like under supervision.
