S3 integration tests are never run

[groldan]

About half the tests for the gwc-aws-s3 blobstore module are integration tests that are never run on Github Actions nor on Jenkins.

mvn verify -o -pl :gwc-aws-s3 2> /dev/null | grep "Tests run" | tail -n 1
[WARNING] Tests run: 54, Failures: 0, Errors: 0, Skipped: 45

This might be due to the difficulty of having an actual AWS S3 bucket to test against. All these tests get ignored and print out a warning message. E.g.:

[INFO] Running org.geowebcache.s3.S3BlobStoreConformanceTest

I guess the tests could be run against a local Minio instead.
