HADOOP-19197. S3A: Support AWS KMS Encryption Context

[raphaelazzolini]

Add the property fs.s3a.encryption.context that allow users to specify the AWS KMS Encryption Context to be used in S3A.

The value of the encryption context is a key/value string that will be Base64 encoded and set in the parameter ssekmsEncryptionContext from the S3 client.

Description of PR

This code change adds a new property to S3A: fs.s3a.encryption.context\

The property's value accepts a set of key/value attributes to be set on S3's encryption context. The value of the property will be base64 encoded and set in the parameter ssekmsEncryptionContext from the S3 client.

This change was merged to trunk by the pull request #6874. This request is to merge the code change to branch-3.4.

How was this patch tested?

Tested in us-west-1 with mvn -Dparallel-tests -DtestsThreadCount=16 clean verify

I added a new test ITestS3AEncryptionSSEKMSWithEncryptionContext.

I added this property to auth-keys.xml

<property>
  <name>fs.s3a.encryption.context</name>
  <value>
    project=hadoop,
    jira=HADOOP-19197,
    component=fs/s3
  </value>
</property>

Then I executed the following tests:

mvn clean verify -Dit.test=ITestS3AEncryption* -Dtest=none

I also executed the test with the following statement in my KMS key:

{
     "Effect": "Deny",
     "Principal": {
         "AWS": "*"
     },
     "Action": "kms:Decrypt",
     "Resource": "*",
     "Condition": {
         "StringNotEquals": {
             "kms:EncryptionContext:project": "hadoop"
         }
     }
}

When using that statement, tests without encryption context fail, and the new test will pass only if the given key-pair is set in fs.s3a.encryption.context.

@steveloughran, I just finished running the integration tests and updated the description. The PR should be good to merge, and then we can close the JIRA.
Thank you!
