Workspaces Web Support
Added mocking for workspaces web (workspaces secure browser)

jamarcelin: @bblommers Hello! I am having some issues here. I have implemented all of the methods that are being tested in the workspaces web test file but when running the tests half of the methods give a "Not Yet Implemented" error. I think the issue is in the urls.py but I am not sure. Any help would be appreciated, thanks!
