HADOOP-18708: S3A: Support S3 Client Side Encryption(CSE) (#6884)

Add support for S3 client side encryption (CSE).

CSE can configured in two modes:
- CSE-KMS where keys are provided by AWS KMS
- CSE-CUSTOM where custom keys are provided by implementing
  a custom keyring.

CSE requires an encryption library:

  amazon-s3-encryption-client-java.jar

This is _not_ included in the shaded bundle.jar
and is released separately.

The version used is currently 3.1.1

### Features
- Supports client side encryption with keys managed in AWS KMS.
- Supports client side encryption with keys managed in AWS KMS (CSE-KMS)
- Supports client side encryption with custom keys by
implementing custom [Keyring](https://docs.aws.amazon.com/encryption-sdk/latest/developer-guide/choose-keyring.html) (CSE-CUSTOM)
- Backward compatible with older encryption clients
like `AmazonS3EncryptionClient.java`(V1) and `AmazonS3EncryptionClientV2.java`(V2)
- encryption settings propagated into jobs through any issued delegation tokens.
- encryption information stored as headers in the uploaded object.
### Compatibility Issues
- The V1 client support reading unencrypted S3 objects, whereas the V3 client does not.
- Unlike the V2 and V3 clients, which always append 16 bytes to a file,
the V1 client appends extra bytes to the next multiple of 16.
For example, if the unencrypted object size is 28 bytes,
the V1 client pads an extra 4 bytes to make it a multiple of 16.
Note: Inorder to workaround the above compatibility issues
set `fs.s3a.encryption.cse.v1.compatibility.enabled=true`
Note: The V1 client supports storing encryption metadata in a separate file with
the suffix "fileName".instruction. However, these instruction files are not
skipped and will lead to exceptions or unknown issues.
Therefore, it is recommended not to use S3A client-side encryption (CSE)
when instruction files are used to store encryption metadata.

[amazon-s3-encryption-client-java](https://github.com/aws/amazon-s3-encryption-client-java/tree/v3.1.1)
which is not packaged in AWS SDK V2 bundle jar and needs to be added separately.
Fix: add amazon-s3-encryption-client-java jar version 3.1.1 to the class path.
