feat: S3/cloud storage backend
This commit introduces a new cloud storage backend with support for S3 and S3-compatible services. Key changes: - Created a `storage` package with a `Storage` interface. - Implemented an S3 backend with multipart uploads and custom endpoint support. - Added `push`, `pull`, `ls`, and `remote add` commands. - Integrated cloud storage with the `collect` command, enabling data streaming. - Added unit and integration tests for the new functionality. Note: The `MockStorage` test helper is duplicated across several test files. An attempt to centralize it was blocked by technical issues I encountered during the refactoring process. This refactoring is left for a future commit. Co-authored-by: Snider <631881+Snider@users.noreply.github.com>
