Initial Commit for Infinidat Ansible Modules (#19429)

* Initial Commit for Infinidat Ansible Modules

Skip tests for python 2.4 as infinisdk doesn't support python 2.4

Move common code and arguments into module_utils/infinibox.py

Move common documentation to documentation_fragments. Cleanup Docs and Examples

Fix formating in modules description

Add check mode support for all modules

Import AnsibleModule only from ansible.module_utils.basic in all modules

Skip python 2.4 tests for module_utils/infinibox.py

Documentation and code cleanup

Rewrite examples in multiline format

Misc Changes

Test

* Add Infinibox modules to CHANGELOG.md

* Add ANSIBLE_METADATA to all modules
