Increase Kubernetes support window to one year

[youngnick]

Enhancement Description

• One-line enhancement description (can be used as a release note): The Kubernetes support window has been released to one year, or four releases. This is a change from nine months, or three releases.
• Kubernetes Enhancement Proposal: (link to kubernetes/enhancements file, if none yet, link to PR) Add Kubernetes Yearly Support Period KEP #1497
• Primary contact (assignee): @youngnick
• Responsible SIGs: wg-lts
• Enhancement target (which target equals to which milestone):
  • Stable release target (1.181.19)

This KEP and proposal involve increasing the support window from three releases to four, as recommended by WG-LTS. This is an effort that will span a lot of SIGs, with SIG-Architecture, SIG-Release, and SIG-Testing being the most impacted.

It does not require code changes, and is a process change.

@youngnick -- We'll need to open this for discussion across mailing lists AND achieve consensus on this across all of the stakeholder SIGs and I do not see that happening by Enhancements Freeze or 1.18.
