   **Apache Airflow version**: 1.10.10
   
   
   **Environment**: 
   
   - **Cloud provider or hardware configuration**:
   - **OS** (e.g. from /etc/os-release):
   - **Kernel** (e.g. `uname -a`):
   - **Install tools**:
   - **Others**:
   
   **What happened**:
   
   I have set the task_concurrency=1 for BashOperator, like below
   sleep_task = BashOperator(task_id=f"task1",
                                          bash_command="sleep 2",
                                          execution_timeout=None,
                                          timeout=20,
                                          retries=3,
                                          retry_delay=timedelta(seconds=30),
                                          task_concurrency=1,
                                          dag=dag)
   It should limit the active tasks for this sleep_task to 1 across dags as per definition.
   
   **What you expected to happen**:
   
   Setting task_concurrency has no impact
   
   **How to reproduce it**:
   
   Add task_concurrency to any operator and try to run many dags at same time, so that these two tasks will be running at same time
   
   **Anything else we need to know**:

   Just tested this on 2.0.0rc3 and it's behaving correctly -- only one task runs at a time..
