**Apache Airflow version**: 1.10.12

**Kubernetes version (if you are using kubernetes)** (use `kubectl version`):

**Environment**:

- **Cloud provider or hardware configuration**:
- **OS** (e.g. from /etc/os-release):
- **Kernel** (e.g. `uname -a`):
- **Install tools**:
- **Others**:

**What happened**:

We have a DAG with ~1300 tasks. After the 1.10.11 -> 1.10.12 upgrade Dag file processing time increased from 3-6sec to 150-250sec.

**What you expected to happen**:

It should be quick. 😄
We extended `AIRFLOW__CORE__DAG_FILE_PROCESSOR_TIMEOUT` to 600 instead of default 50.

**How to reproduce it**:
<!---

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

- Minikube https://minikube.sigs.k8s.io/docs/start/
- Kind https://kind.sigs.k8s.io/docs/user/quick-start/

If this is a UI bug, please provide a screenshot of the bug or a link to a youtube video of the bug in action

You can include images using the .md style of
![alt text](http://url/to/img.png)

To record a screencast, mac users can use QuickTime and then create an unlisted youtube video with the resulting .mov file.

One task processing in our Dag takes ~0.3sec. The call to `get_failed_dep_statuses` method.
If the new `NotPreviouslySkippedDep` is removed from dependencies, it's quick again (0.001s and less).

**Anything else we need to know**:

<!--

How often does this problem occur? Once? Every time etc?

Any relevant logs to include? Put them here in side a detail tag:
<details><summary>x.log</summary> lots of stuff </details>
