SO-3720 BuildingBlockRollback lookup table

Issue-ID: SO-3720

BuildingBlockRollback lookup table will indicate the rollback BB to take;
this is the first part for simplifying WorkflowActionBBTasks logic:
instead of doing string matching, we just do a lookup of a block to call
to perform the rollback operation.
In some cases, the Action is set as well - this would be needed for certain
BBs, in that case, there is a corresponding rollbackAction as well.
