kcidb/oo/__init__: methods for getting fluster tests stats

Add `Node.sort_fluster_tests_by_platform` to create a sorted
dictionary by platform with its associated passed and failed tests.
Add `Node.get_fluster_stats` for getting number of passed and failed
tests for all enabled fluster tests per platform.
