Move repository-s3 fixture tests to QA third party project

This commit moves the repository-s3 fixture test added in elastic#29296 in a
new `qa/third-party/amazon-s3` project. This new project allows the
REST integration tests to be executed using the real S3 service when
all the required environment variables are provided. When no env var
is provided, then the tests are executed using the fixture added
in elastic#29296.

The REST tests located in the plugin project now only verify that the
plugin is correctly loaded.

The REST tests have been adapted to allow a bucket name and a base path
to be specified as env vars. This way it is possible to run the tests
with different base paths (could be anything, like a CI job name or a
branch name) without multiplicating buckets.
