Function to get list of generated proxies

Change-Id: I1847950f0896c2c5685f683557f228de2197cef5
Added new doc page for servermanager proxies

Exclude the generated proxies from the simple module doc page and document them
on a different page.
Removed the PARAVIEW_DOCUMENTATION_SKIP_ADD_FUNCTIONS workaround.
