[rust] generate a dev version and install prod version from crates.io

[iunanua]

Motivation

Enable prod tests for rust tracer

Changes

Modify install_ddtrace.sh‎ to:

• dev: generate dinamically a version for the tracer based on: the next minor version, -dev sufix and +<githash> (for example 0.4.0-dev+961440933807d6354f7af5098e61e605ed137495) and use it when adding the dep via path
• prod: add the latest published crate in crates.io

I have modified test_compute_libraries_and_scenarios.py‎ and compute_libraries_and_scenarios.py to enable prod and it seems it's working but it might be necessary to modify others.

Workflow

1. ⚠️ Create your PR as draft ⚠️
2. Work on you PR until the CI passes
3. Mark it as ready for review
   • Test logic is modified? -> Get a review from RFC owner.
   • Framework is modified, or non obvious usage of it -> get a review from R&P team

🚀 Once your PR is reviewed and the CI green, you can merge it!

🛟 #apm-shared-testing 🛟

Reviewer checklist

• Anything but tests/ or manifests/ is modified ? I have the approval from R&P team
• A docker base image is modified?
  • the relevant build-XXX-image label is present
• A scenario is added, removed or renamed?
  • Get a review from R&P team

LGTM but bumping the minor means that if you work on a patch to the previous release it might not run all the tests
