When we do fs.getFileStatus().getLen() to get the content length of the
encrypted file, it is not the same as the original length and hence, the tests
are breaking.
```[INFO]

```
Failures other than S3-CSE tests are config related
```

```
When I remove the checks for file content Lengths from the tests, the tests
run successfully, hence, the Key-wrap Algo and Content Encryption Algo are used
as intended successfully.
One possible way we explored to tackle the padding issue was to tweak the
s3GetFileStatus call to return a FileStatus with "UNENCRYPTED_CONTENT_LENGTH"
header which comes in the user metadata, but this would still break where we
don't get these headers to do our tasks. Hence, consistency of content Length
needs to be maintained.
P.S: Need more tests to validate that even with tweaking, we are breaking
some tests.
