[WIP] Perf ui improvements

I've made a number of improvements to the UI performance testing code:

* Per Page statistics csv output now
 * Records # of Samples, min/max/avg/std and 90th percentile values for timing and query count values
* Added additional accordions to vm_infra and vm_cloud pages
* Added reports page under Cloud Intelligence
* Refactored existing code into separate files for readability/maintainability
* Records uncached query counts automatically now
* Refactored the ui_bench yaml for more granularity on how many times a page is browsed to
Does this fixture work properly for you? We are generally abandoning this fixture in favour of testgen which parametrizes the test with providers (that minimizes errors caused by one angry provider destroying all tests).
