References issue [#27979](https://github.com/apache/airflow/issues/27979) `EmrAddStepsOperator` doesn't kill the step on EMR when a clear is called on UI. Unlike other operators where process gets killed once clear is called, here, nothing is affected to the step on EMR, stays in the same state. With this PR, before a new step is added or when clear is called, if pre-existing step is already in RUNNING/PENDING state, its marked for cancel from EMR list of steps. It will instantaneously makes the cluster available to run current step and wouldn't keep on waiting for existing step to finish <!-- Thank you for contributing!
