Create Reporting Menu and Test Page

We need to have a Reporting menu added to the navigation toolbar in OpenLMIS v3. Eventually it will include one page per cluster of reports, but for now we just need a test page where we can embed iFrames and test SSO, row-level filtering, and formatting of iFrames within OLMIS.

The menu should be called "Reporting" and the page underneath it should be called "iFrame Testing"

Acceptance criteria:

• The "Reporting" menu exists with the "iFrame Testing" page within it
