Monitor infra directory structure changes.
- Split the js files per tab.
- All js files will now be in their respective feature/js 
e.g : webroot/monitor/infra/computenode/ui/js will contain the js files
related to computenode and files are split based on tabs.
- The loadResourcesFromMenuObj in web-utils.js modified to accomodate
the new directory structure.
- Common js/view files across features can now be declared in parent
elements in menu.xml. 
For e.g if there are js and view files common across monitor infra pages
they can now be declared only once directly under infrastructure label
level. And if they are common across all monitor pages they may be
declared under MONITOR label and these files will now automatically
loaded for all child features.
