Introduce qa subprojects of :modules:repository-s3 (elastic#126274)

Today we have some special-case test classes in `:modules:repository-s3`
within the same source root as the regular tests, with some trickery to
define separate Gradle tasks to run them with their special-case
configs. This commit simplifies the build by just moving each of these
classes into its own Gradle project.
