Add v1 execution documents and pre-deploy change list ...

Adds the eight v1-do-doc-NN-*.md execution documents covering the v1
  deploy from pre-flight through Magnum CAPI driver graft (Batches A/B/C
  of the do-doc drafting work). Final two documents (tenant + validate)
  follow in Batch D.

  Also adds docs/v1-pre-deploy-fixes.md (v2) - the 9-commit change list
  that brings the repo into its pre-deploy hygiene state. Subsequent
  commits in this push implement that change list.
