Drop CentOS 7 support in RAPIDS 24.06

[bdice]

We plan to drop CentOS 7 (which uses glibc 2.17) in RAPIDS 24.06. https://docs.rapids.ai/notices/rsn0037/

At this time, the new minimum glibc supported by RAPIDS will become 2.28 (used by Rocky 8), because that is the oldest glibc of any operating system we currently support.

This issue documents some of the work items needed to complete the drop in platform support.

Early 24.06

• Drop test configurations with CentOS 7 (glibc 2.17) and Ubuntu 18.04 (glibc 2.27) from https://github.com/rapidsai/shared-workflows. (We have already dropped Ubuntu 18.04 support.)
  • rapidsai/shared-workflows#192
  • rapidsai/shared-workflows#205
  • Testing PR: rapidsai/cudf#15323
  • Remove the shared-workflows NEW_MANYLINUX_MATRIX. After dropping CentOS 7, RAPIDS will not build manylinux_2_17 tags. RAPIDS will only produce wheels that support manylinux_2_28 tags but nothing older.
  • Remove build-2_28-wheels option: rapidsai/shared-workflows#195
• Unpin/update GitHub Actions that were pinned to older versions because of updates to GitHub Actions using Node 20 (which does not support CentOS 7)
  • rapidsai/shared-workflows#178
  • Check on shared-workflows PRs from renovate, including (but not limited to):
    • rapidsai/shared-workflows#134 (comment)
    • rapidsai/shared-workflows#135 (comment)
  • https://github.com/rapidsai/cudf-pandas-integration/pull/109
• Spark-RAPIDS:
  • NVIDIA/spark-rapids#10496
  • NVIDIA/spark-rapids-jni#1991
  • NVIDIA/spark-rapids#10805
  • rapidsai/cudf#15608

Before 24.06 release

• Update various release scripts (especially wheel related ones which key on the manylinux version): tracking issue
  • PRs listed here.
• Update shared-actions to use actions with Node 20 (to avoid deprecation warnings)
  • rapidsai/shared-actions#9
• Drop centos7 and ubuntu18.04 from the https://github.com/rapidsai/ci-imgs matrix - rapidsai/ci-imgs#139
  • Not required for release. Wait until 24.04 has shipped (and simmered for a bit, in case hotfixes are needed).
• Drop centos7 from miniforge-cuda matrix: rapidsai/miniforge-cuda#66

After 24.06 release

• Update installation guide - rapidsai/docs#513
• Update rapids.ai homepage - rapidsai/rapids.ai#379

Feel free to edit this checklist with more items.

We talked with Ray and he resolved the remaining issues needed before 24.06 ships

The remaining items are to be done after 24.06 ships

So nothing to do until 24.06 ships
