Fix analytics systemless test failure

The latest thrift package is incompatible with pycassa. Therefore, pin
dependency on compatible version of thrift.

Disabled the following flaky tests:
- test.test_analytics_sys.AnalyticsTest.test_07_table_source_module_list
- test.test_analytics_uve.AnalyticsUveTest.test_05_collector_ha
