Do not use config.lua but import own config

[Michael Rolli]

Is your feature request related to a current shortcoming? Please describe.
Using config.lue directly in LunarVim works as expected but comes with several downsides:

• Re-installing LunarVim from scratch overwrites the config (ok, backups are made)
• Chances are that config.lua comes with changes, which need to merged over manually
• One tends to build a monolithic config.lua and forget about splitting in logical chunks

Describe the solution you'd like
Do not edit/use config.lua directly but instead create a modular own config and only import the main:

--- Add this in config.lua as the only change
require('rollisch')

--- have this config structure:
rollisch/init.lua
rollisch/keybindings.lua
rollisch/trouble.lua

Still version the config.lua to be able to investigate the history of this file in my repository.

Use namespace user instead of rollisch, is shorter and sounds more like me
