chore(rbo): MCOL-6143: Settle down rbo as a separate lib for Unittesting ( #3708 )
...
* fix builds
* MCOL-6143: rbo as a separate library
* Move get_unstable_optimizer out of rbo, move findStatisticsForATable to header bo be (dirty fix, but cuts the corner)
* Add some helpers to a headerfile for unittesting
* Simple unittests with some mocks
