Maximum of nested Level in Navbar should be assigned by global config file.

[mildronize]

Problem

As you can see in the code: /src/components/Sidebar/contentTree.js

// ...
// Maximum Deep level of render Nav menu (Start with 0)
const limitDeepLevel = 3;
// ...

this setting is not assigned by global config file.

Expected Behavior

It should be assign in file /config/config.yml

# ...
features:
  sidebar: 
    limitDeepLevel: 3  # Maximum Deep level of render Nav menu (Start with 0)
# ...
