Cannot import name 'cached_property'

## Instructions To Reproduce the 🐛 Bug:
1. Full runnable code or full changes you made:
```
!python -m pip install pyyaml==5.1
import sys, os, distutils.core
# Note: This is a faster way to install detectron2 in Colab, but it does not include all functionalities.
# See https://detectron2.readthedocs.io/tutorials/install.html for full installation instructions
!git clone 'https://github.com/facebookresearch/detectron2'
dist = distutils.core.run_setup("./detectron2/setup.py")
!python -m pip install {' '.join([f"'{x}'" for x in dist.install_requires])}
sys.path.insert(0, os.path.abspath('./detectron2'))

import detectron2
from detectron2.utils.logger import setup_logger
setup_logger()

# import some common libraries
import numpy as np

# import some common detectron2 utilities
from detectron2 import model_zoo
from detectron2.engine import DefaultPredictor
from detectron2.config import get_cfg
from detectron2.utils.visualizer import Visualizer
from detectron2.data import MetadataCatalog, DatasetCatalog
```
2. What exact command you run: from detectron2 import model_zoo
3. __Full logs__ or other relevant observations:

4. please simplify the steps as much as possible so they do not require additional resources to
run, such as a private dataset.

## Expected behavior:

It seems to have trouble importing model_zoo from detectron2. A couple days ago it just worked fine.

## Environment:

Provide your environment information using the following command:
```
------------------------------- -------------------------------------------------------------------------------
sys.platform linux
Python 3.7.12 | packaged by conda-forge | (default, Oct 26 2021, 06:08:53) [GCC 9.4.0]

If your issue looks like an installation issue / environment issue,
please first try to solve it yourself with the instructions in
https://detectron2.readthedocs.io/tutorials/install.html#common-installation-issues

Start at detectron2/utils/events.py and reproduce the import under the reported Python 3.7 environment. Check the installation instructions and compatibility expectations for the reported Python and PyTorch setup. Done means a supported clean installation imports detectron2.model_zoo without the cached_property or detectron2._C errors.
