- This encapsulates all plugin related functionalities into the plugins/
folder (and pluginconfig/) instead of relying on utility file.
- It also renames utility/plugins.lua to a more sensible
plugins/packer.lua as it actually only applies for packer plugin
manager.
- The plugins.lua file is now split into 2 files, first holding the list
of all plugins plugins/plugin_list.lua and second one holding the
logic of bootstrapping and running startup on packer.
