Determine and document paid technical support policy for GET
Relevant discussion from https://gitlab.com/gitlab-org/quality/gitlab-environment-toolkit/-/issues/327#note_778832510:
@grantyoung
GET currently doesn't follow the two last major version guidance as the complexity would be simply unmanageable. While we could be removing RepMgr from v2.0.0 previous versions of GET will still be available for current users.
@weimeng
Understood. Although that does raise a different question: When do we stop supporting old GET releases? I'll create a separate issue for this later.
@joshlambert
Should we apply the standard GitLab maintenance policy?
