feat(modules): add OpenFGA module

[giggsoff]

Add OpenFGA testcontainer module

[cbernard-rm25]

This is super useful. I am trying to run something like this locally but not having much success. Would love to see this native to testcontainers-python.

Closed #806

So we got:

modules/openfga/tests/test_openfga.py:1: in <module>
    from testcontainers.openfga import OpenFGAContainer
modules/openfga/testcontainers/openfga/__init__.py:17: in <module>
    from openfga_sdk import ClientConfiguration
E   ImportError: cannot import name 'ClientConfiguration' from 'openfga_sdk'

looks like a completability issue.

Checking the lock file we get:

name = "openfga-sdk"
version = "0.1.1"

This is from Jan 18, 2023

The current project's supported Python range (>=3.9,<4.0) is not compatible with some of the required packages Python requirement:
  - openfga-sdk requires Python >=3.10, so it will not be installable for Python >=3.9,<3.10
