Provide a script to run during a new crate release

[stefano-garzarella]

We are realizing that during the release of a new version of a crate, we need to do some checks, such as checking that all codeowners are also on crates.io [see https://github.com/rust-vmm/rust-vmm-ci/issues/142], run cargo-semver-checks [see https://github.com/rust-vmm/rust-vmm-ci/issues/135], etc.

The best thing then might be to provide a single script where we do all the checks and if everything passes, proceed with the release.

• Add a new script (maybe in https://github.com/rust-vmm/rust-vmm-ci) to do the release (with checks)
  • Include Add cargo-semver-checks rust-vmm-ci#135
  • Include Check for correct crates.io ownership for every crate in the repository rust-vmm-ci#142
• Update the documentation in https://github.com/rust-vmm/community/blob/main/docs/crate_release.md

For reference, here's the script I used to manually check owners:

As for semver checks, since there are a lot of inter-dependencies in the rust-vmm ecosystem, maybe we can check that all crates build with new (minor) versions?
