[KSchopmeyer]

more-itertools Version 8.11.0 not does not support Python version < 3.6. Pywbem test failures include:

1. Test failure for tests based on (python 3.5, macos and windows, latest). The test failure was:
   Fails in safety test:
   File "/Users/runner/hostedtoolcache/Python/3.5.10/x64/lib/python3.5/site-packages/more_itertools/init.py", line 1, in
   from .more import * # noqa

   TypeError: slice indices must be integers or None or have an index method
   make: *** [Makefile:843: safety_py3.9.done] Error 1

Proposed solution, limit maximum version of more-itertools for now until the issue is resolved within more-itertools

more-itertools is a dependency for pytest per pipdeptree

• pytest [required: >=3.6, installed: 4.4.0]
  • atomicwrites [required: >=1.0, installed: 1.4.0]
  • attrs [required: >=17.4.0, installed: 21.2.0]
  • more-itertools [required: >=4.0.0, installed: 8.11.0]

NOTE: more_itertools stopped supporting python 2.7 with version 6.0.0 and that is documented in their setup

See more-itertools issue more-itertools/more-itertools#578 which requests that the limitation become part of the setup and more-itertools PR more-itertools/more-itertools#579 that defines the change to setup.
