[ExternalStorage] AWS S3 cloud

PR Description:

Description

This PR adds support for AWS S3 cloud as a new way to store external files, using external storage UI from qgis/QGIS#44533.

Funded by Métropole Grand Lyon

AWS S3 Signature V4 authentication

AWS uses a specific authentication which is here implemented in a new QGIS Auth method named "AWS S3".

Minio for testing

MinIO is a high performance object storage solution that provides an Amazon Web Services S3-compatible API and supports all core S3 features.

It is used here in CI to simulate AWS S3 cloud for the new python test created for this feature.

Technical notes

A factorization of WebDAV implementation with AWS implementation lead to some file and classes renaming from WebDAV to the more generic HTTP word.
