pipelineState holds a list of pipeline tasks with resolved conditions and pipeline resources. pipelineState also holds a taskRun for each pipeline task after the taskRun is created.

candidateTasks contains a list of pipeline tasks that can be scheduled next. This list of candidates is derived based on the successfully finished tasks. A task is considered as candidate if its all parents have finished executing successfully. Also candidates are initialized with all root/s of DAG tasks.

GetNextTasks returns a list of tasks which should be executed next. This list is derived based on candidateTasks. GetNextTasks returns a list of candidates for which pipelineState does not have any taskRun or a list of failed
