minio into containers for s3 test suite

Per MDEV-23662 and MDEV-23650 we're soon going to be able to test s3 in buildbot.

I expect to be writing a few issues and getting some tests masked in addition to bugs like MDEV-23648.

This will need the server minio (https://dl.min.io/server/minio/release/linux-amd64/ and relative links), and the client mc https://dl.min.io/client/mc/release/linux-amd64/. These are golang built static executables.

These at least for me were painfully slow to download.

How to run the tests is listed:
