gc: Add libraries for HDFS support

[vfxcode]

This PR is meant to allow Nessie GC to run in self-hosted Hadoop clusters using HDFS.

The original Error when using HDFS stored warehouses is the following:

Caused by: org.apache.iceberg.exceptions.RuntimeIOException: Failed to get file system for path: hdfs://hadoop-namenode:9000/user/iceberg/...../metadata/v4603.metadata.json

This PR was tested in a couple of our environments and it seems to work mostly correct. We could not observe any data loss and the files that remain seem to be the expected ones.

There is another way to make it work without this patch, by using the hadoop-hdfs and hadoop-hdfs-client jars directly from maven using this command line:

java -cp "/tmp/hadoop-hdfs-3.4.2.jar:/tmp/hadoop-hdfs-client-3.4.2.jar:/nessie-gc.jar" org.projectnessie.gc.tool.cli.CLI gc

Not sure if I am missing anything from the bigger picture to be honest as I am not very familiar with Nessie yet.

Thanks for your contribution, @vfxcode !

[dimas-b]

should this be intTestRuntimeOnly like iceberg-aws?

[dimas-b]

runtimeOnly like iceberg-aws?

[dimas-b]

Would it be possible to add a test similar to ITSparkIcebergNessieS3 but for HDFS?

[vfxcode]

I am not very familiar with Java let alone with Java Test frameworks.
Coudl I take a look at it but at a later time to not block this PR?

[dimas-b]

How do we know GC works with HDFS now?

[dimas-b]

Manual testing is fine in this case, IMHO... but if CI-based tests are not practical, we should probably not add HDFS to "test" dependencies for the sake of clarity.

[vfxcode]

@dimas-b I will do another round of tests with the changes you proposed and verify that it still works
