[g11tech]

Since v1.2.0-rc.3 introduce new test scenarios as well as capella hardfork, some of the test cases have been programmed to skip via PR #4456 and should be enabled as soon as they are supported/fixed.

This issue compiles incomplete changes up to v1.2.0-rc.3 and closes previous trackers #3945 and #4060
