Problem:

We need to port the changes made on the os-upgrade branch to develop, for the 2025.4.0.0 release.

Solution:

• Note, this will need to be integrated simultaneously with all the other LTS changes on other repositories, after code-complete.
• This PR has all the changes made on the os-upgrade branch, cherry-picked and squashed into a single commit for integration on the develop branch.
  • DLPX-93404 LTS 24.04: delphix-rust must explicitly state that it provides rustfmt & cargo-fmt (DLPX-93404 LTS 24.04: delphix-rust must explicitly state that it provides rustfmt & cargo-fmt #26)
  • DLPX-93326 Add package containing rust source files (DLPX-93326 Add package containing rust source files #25)
  • DLPX-93311 24.04 LTS upgrade: kernel builds continue to fail due to rustc conflict (DLPX-93311 24.04 LTS upgrade: kernel builds continue to fail due to rustc conflict #23)
  • DLPX-93264 24.04 LTS upgrade: kernel builds fail due to rustc conflict (DLPX-93264 24.04 LTS upgrade: kernel builds fail due to rustc conflict #21)
