dataclasses backport required for Python 3.6

See original GitHub issue

Describe the bug Since #567, dataclasses is being used. This module is not in Python 3.6, so the backport needs to be installed.

To Reproduce Steps to reproduce the behavior:

$ python --version
> python 3.6.11
$ python -m venv .env
> ...
$ source .venv/bin/activate
$ pip install checkov
> ...
$ checkov --version

Traceback (most recent call last):
  File "/tmp/test/.env/bin/checkov", line 2, in <module>
    from checkov.main import run
  File "/tmp/test/.env/lib/python3.6/site-packages/checkov/main.py", line 15, in <module>

    from checkov.serverless.checks.function.base_function_check import BaseFunctionCheck
  File "/tmp/test/.env/lib/python3.6/site-packages/checkov/serverless/checks/function/base_function_check.py", line 5, in <module>

  File "/tmp/test/.env/lib/python3.6/site-packages/checkov/serverless/checks/function/registry.py", line 1, in <module>
    from checkov.serverless.base_registry import ServerlessRegistry
  File "/tmp/test/.env/lib/python3.6/site-packages/checkov/serverless/base_registry.py", line 2, in <module>
    from dataclasses import dataclass
ModuleNotFoundError: No module named 'dataclasses
#
# To resolve
#
$ pip install dataclasses
$ checkov --version
1.0.544

Expected behavior setup.py should have a dependency for dataclasses, if the Python version is 3.6.

Desktop (please complete the following information):

OS: Ubuntu 20.04
Checkov Version 1.0.544

let’s update setup.py to support only python 3.7 and above.
