Spike - Investigate feasibility of generating terraform plans on PR for latter stages of new-environments workflow.

[mikereiddigital]

User Story

As a Modernisation Platform Engineer
I would like to see terraform plan output to delegate-access, signle-sign-on and member-bootstrap as part of a PR when adding / amending sso access for an existing environment.
So that we can identify any issues prior to merge & so reduce apply failures.

Value / Purpose

The implementation of the workflow is multi-phased with latter stages dependent on the successful completion of earlier stages and due to the same workflow new-environment workflow running whether it is a whole new account or just a new sso access. Because of the multi-staged approach and with the workflow only running from the main branch, we are unable to see a full plan for the latter stages without a merge.

The availability of pre-merge plan output for the latter stages for changes that are not affecting an account could be beneficial if it is feasible to implement.

Context / Background

See ticket #9226 and the slack thread mentioned.
