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.
