Restore integration tests (#2620)

* restored test_consensus

* restored test_sync

* run integration tests only on CI

* use single test-thread for integration tests

* post-merge fix

* panic when integration test runs for too long

* add some traces to integration logs

* manual wait -> timeout

* post-merge fix

* post-merge fix
