Python 3.10 compatibility issue

#### Environment details



  - OS type and version: Windows 10

  - Python version: `python --version`  3.10.1

  - pip version: `pip --version` 21.2.4

  - `google-api-python-client` version: `pip show google-api-python-client` - 2.33.0



uritemplate package 3.0.0 is not compatible with python 3.10. Need to update the requirements.
