[Operator] External artifact FileAlreadyExistsException

The Operator makes use of the server images SERVER_LIBS directory to download and extract dependencies using the Infinispan CLI. However, after on container restart it's possible for this step to fail due to a FileAlreadyExistsException during the extraction phase as the dependency has already been resolved on the filesystem.

To prevent this, we should always set the --overwrite flag when calling ./cli.sh install to download the SERVER_LIBS.
