Initial update to 6.0.0-dev0: remove support of ansible-core<2.16.0 and k8s inventory plugin

[yurnov]

SUMMARY

This is initial to prepare the main branch to version 6.0.0 (6.0.0-dev0 in galaxy.yml) and includes following braking changes:

• removed support of ansible-core<2.16.0 as 2.15 reach EOL in Nov 2024;
• removed the k8s inventory plugin that was deprecated in release 3.0.0.

ISSUE TYPE

• Feature Pull Request

COMPONENT NAME

• Documentation
• galaxy.yml
• inventory/k8s.py

ADDITIONAL INFORMATION

The initial version of this PR doesn't remove tests/sanity/ignore-2.14.txt and tests/sanity/ignore-2.15.txt, and CI part will require removing version 2.15 from the matrix in https://github.com/ansible-network/github_actions, so, we have external dependency here.

Failed sanity is 2.15 with:

ERROR: Output on stderr from ansible-doc is considered an error.

Command "ansible-doc -l --json -t filter kubernetes.core" returned exit status 0.
>>> Standard Error
Warning: : Collection kubernetes.core does not support Ansible version
2.15.13.post0

That is expected. To be corrected in the https://github.com/ansible-network/github_actions
