adding notebooks for data conversion and encryption

- *handling_kms_encrypted_data.ipynb*: How to use Server Side KMS encrypted data with Amazon SageMaker training works. The IAM role used for S3 access needs to have permissions to encrypt and decrypt data with the KMS key.
- *parquet_to_recordio_protobuf.ipynb*: How to convert Parquet data format into the recordIO-protobuf format that many SageMaker algorithms consume.
- *working_with_redshift_data.ipynb*: Demonstrates how to copy data from Redshift to S3 and vice-versa.
