On opening a new series we need to:

• create new repositories seeded from the unstable branches

  • ubuntu-<series>

  • ubuntu-<series>-meta

  • ubuntu-<series>-signed

• mainline builds
  • lib-build: add new series to ubuntu_series=""
  • cod-source-trigger: add new series to series lists
• cve-tools
  • cves-autotriage.conf: add new series to series list
  • cve-matrix/Makefile.combo: add new series to PARTS_linux
