HADOOP-16794. S3A reverts KMS encryption to the bucket's default KMS key in rename/copy.

AreContributed by Mukund Thakur.

This addresses an issue which surfaced with KMS encryption: the wrong

KMS key could be picked up in the S3 COPY operation, so

renamed files, while encrypted, would end up with the

bucket default key.

As well as adding tests in the new suite

ITestS3AEncryptionWithDefaultS3Settings,

AbstractSTestS3AHugeFiles has a new test method to

verify that the encryption settings also work

for large files copied via multipart operations.
