[community] [docs] Draft New "Ansible with z/OS" section

[ketankelkar]

Draft the content for a new section similar to the Using Ansible on Windows and BSD page.

Intention-

In this section we would inform users of the required environment variables needed to allow for community modules to manage z/OS nodes. We would also describe when it might be good to use one of the ibm_zos_core modules over a community one, for example, when to use copy over zos_copy.

Improving the documentation would provide a better user experience when leveraging Ansible community modules with z/OS and would be better to have this information in the community docs instead our current Ansible z documentation.

Roughly, we’re thinking, a new sub-section under the “USING ANSIBLE” section, with sub-topics:

• ‘Using Ansible with z/OS’:

  • Configuring a z/OS managed node
  • Configuring environment variables for use with z/OS managed nodes
  • Configuring python, ssh and other dependencies

• Capabilities for z/OS target nodes within the bounds of Ansible builtin.community modules

  • Expand on UTF-8 and EBCDIC
    • (EBCDIC is a very common and prevalent encoding on z/OS mainframes)
  • Explaining when to use the community modules over the ibm_zos_core collection modules.
  • Expanding the scope for Ansible with z/OS managed nodes:
  • link out to z_ansible_collections_samples GH repo
    • https://github.com/IBM/z_ansible_collections_samples
  • link out to the unified IBM Z certified collections docs site
    • https://ibm.github.io/z_ansible_collections_doc/index.html

This includes the actual wording/phrasing, the formatting, examples, etc.

• Since the repo is public, it should be possible to mock up the new page and achieve a realistic "look-and-feel".
