Fixes: FRMW-2858
This PR merge the modules exported by the plugins with the modules defined within the user config. As a result, all modules get loaded without changing the internals of the loader.
However, you cannot disable the module of a plugin by re-adding it to the `modules` array. That is something we should handle separately.
We've added the breaking change label because of the following fix:
We did broke the ability to completely disable modules in the past pr's, in this pr we re add the ability to disable a module and that this modules does not get loaded at all. ([here](6dd164f783))
