**Apache Airflow version**: 2.0.1 Git Version:.release:2.0.1+beb8af5ac6c438c29e2c186145115fb1334a3735

**Kubernetes version (if you are using kubernetes)** (use `kubectl version`): 1.17.17-gke.2800

**Environment**:

- **Cloud provider or hardware configuration**: GKE (Kubernetes)
- **OS** (e.g. from /etc/os-release): Debian GNU/Linux 10 (buster) - docker image python:3.8-slim-buster
- **Kernel** (e.g. `uname -a`): Linux bd0d5605654a 4.15.0-140-generic #144-Ubuntu SMP Fri Mar 19 14:12:35 UTC 2021 x86_64 GNU/Linux
- **Install tools**: pip
- **Others**: Python 3.8, Kubernetes Executor, Docker

**What happened**:
Pod template contained non existing volume which caused pod to be impossible to run. The volume existed before but was deleted. Task in Airflow was also stuck at "queued".
Even after clearing task these pods stayed stuck in container creating and it seems that they need to be manually deleted.

Pods are stuck with
```
Unable to attach or mount volumes: unmounted volumes=[secret-volume], unattached volumes=[google-key airflow-logs secret-volume]: timed out waiting for the condition
MountVolume.SetUp failed for volume "secret-volume" : secret "airflow-secret-14610" not found
```

Configuration:
```
AIRFLOW__KUBERNETES__DELETE_WORKER_PODS=True
AIRFLOW__KUBERNETES__DELETE_WORKER_PODS_ON_FAILURE=True

```

**What you expected to happen**:
I would expect Airflow to delete pods that are not possible to be created, at least after clearing the task.

**How to reproduce it**:
Create a pod template with a volume and later delete that volume without pausing DAGs
<!---

As minimally and precisely as possible. Keep in mind we do not have access to your cluster or dags.

If you are using kubernetes, please attempt to recreate the issue using minikube or kind.

## Install minikube/kind

**Anything else we need to know**:
It happens all the time and pods are not being deleted.
