PR #72591
This change:
* Adds an artifacts manager that abstracts away extracting the
metadata from artifacts, downloading and caching them in a
temporary location.
* Adds `resolvelib` to direct ansible-core dependencies[0].
* Implements a `resolvelib`-based dependency resolver for
`collection` subcommands that replaces the legacy
in-house code.
This is a dependency resolution library that pip 20.3+ uses
by default. It's now integrated for use for the collection
dependency resolution in ansible-galaxy CLI.
* Refactors of the `ansible-galaxy collection` CLI.
In particular, it:
- reimplements most of the `download`, `install`, `list` and
`verify` subcommands from scratch;
- reuses helper bits previously moved out into external modules;
- replaces the old in-house resolver with a more clear
implementation based on the resolvelib library[0][1][2].
* Adds a multi Galaxy API proxy layer that abstracts accessing the
version and dependencies via API or local artifacts manager.
* Makes `GalaxyAPI` instances sortable.
* Adds string representation methods to `GalaxyAPI`.
* Adds dev representation to `GalaxyAPI`.
* Removes unnecessary integration and unit tests.
* Aligns the tests with the new expectations.
* Adds more tests, integration ones in particular.

* supported Ansible version validation on collection loads
