Add better support for the new RC API

[christophe-papazian]

Motivation

We need to be able to

• delete RC files (for example, one click deactivation is working like that)
• keep track of RC states between tests of a same scenario

Remote config works like a permanent state represented as a set of files (configurations) that we can modify or delete. This PR changes the API to reflect that.

Please remember that each scenario using remote config tests share a single state among all tests of the scenario. No assumption should be made on the tests order, so each setup should set the desired state with reset and set_config at first (at test or class level).

Changes

• refactor the api by exposing a single rc_state object
• rename add_client_config to set_config
• add del_config and reset to delete RC files in the current state
• automatically keep track of config and files version to ensure the next send is taken into account as expected
• allow empty list of files to be sent to reset everything and wait for confirmation (using global version watching)
• update documentation
• update all previous tests using the new API
• Add a more complex test enabling and disabling ASM 4 times in a row, waiting and testing at each step.
• Update all manifests

Workflow

1. ⚠️ Create your PR as draft ⚠️
2. Work on you PR until the CI passes (if something not related to your task is failing, you can ignore it)
3. Mark it as ready for review
   • Test logic is modified? -> Get a review from RFC owner. We're working on refining the codeowners file quickly.
   • Framework is modified, or non obvious usage of it -> get a review from R&P team

🚀 Once your PR is reviewed, you can merge it!

Reviewer checklist

• If PR title starts with [<language>], double-check that only <language> is impacted by the change
• No system-tests internal is modified. Otherwise, I have the approval from R&P team
• CI is green, or failing jobs are not related to this change (and you are 100% sure about this statement)
• A docker base image is modified?
  • the relevant build-XXX-image label is present
• A scenario is added (or removed)?
  • Get a review from R&P team
