MINOR: lua: refactor the Lua object registration
All the HAProxy Lua object are declared with the same pattern:
- Add the function __tosting which dumps the object name
- Register the name in the Lua REGISTRY
- Register the reference ID
These action are refactored in on function. This remove some
lines of code.
