Interferes based queries optimized (#548)

* Optimized implementation of EquivalenceQuery.

Signed-off-by: Tanya <[email protected]>

* Added VacuityQuery and RedundancyQuery optimized implementation.
Keeping optimized properties separated per rule (instead of the union of all policy rules)
Fixed handling HostEPs in optimized implementation.

* Ignoring 'complex function' lint error.
Returning 'passed' code for skipped queries.

* Fixed domain updating mechanism per rule (to avoid activating multiple times for the same rule, for example when a rule appears twice in a config).

* Fixed lint errors

* Enabled strongEquivalence optimized implementation.

Signed-off-by: Tanya <[email protected]>

* Implemented optimized ContainmentQuery.
Commented out containment fullExplanation result comparison in tests, since optimized solution gives more accurate result that differs from the original expected result, and thus the test fails.

* Enabled optimized TwoContainmentQuery and PermitsQuery.
Commented out twoWayContainment fullExplanation result comparison in tests, since optimized solution gives more accurate result that differs from the original expected result, and thus the tests fail.

* Fixed small inaccuracy in handling host endpoints in optimized solution.
Adding docs

* Implemented optimized InterferesQuery

* Small improvement in print differences for two config queries
Commenting out detailed difference result for some tests, since optimized implementation results are sometimes more detailed than the original ones.
