Support for ansible-core versions 2.11 and 2.12 will be dropped in v5.0.0

[briantist]

SUMMARY

2.11 is EoL already, and 2.12 will be EoL right around when v5.0.0 is released, which should be around May 2023.

What this means

• We will no longer test against these versions in CI.
• New and existing code will not be required to support these.
• Code that currently exists solely to support these versions may be removed in this release, or at a later time.
• PRs proposed to (re)add compatibility with these versions will be considered if the changes have full test coverage (it still will not be tested against the EoL versions, but it must be tested and working against current versions), and if the changes do not make future maintenance harder. Each will be considered on a case-by-case basis and may not be accepted.
• Requests to (re)add compatibility with unsupported versions will be closed. Only an actual contribution of such a change will be considered.
