Update GATK AWS phone-home configuration

-Switch to using new GSA AWS account for storage of phone home data

-Use DNS-compliant bucket names, as per Amazon's best practices

-Encrypt publicly-distributed version of credentials. Grant only PutObject
 permission, and only for the relevant buckets.

-Store non-distributed credentials in private/GATKLogs/newAWSAccountCredentials
 for now -- need to integrate with existing python/shell scripts
 later to get the log downloading working with the new account
