Domain logging should be enabled for Elastic Search domains

# METADATA
# title: Domain logging should be enabled for Elastic Search domains
# description: |
#   Amazon ES exposes four Elasticsearch logs through Amazon CloudWatch Logs: error logs, search slow logs, index slow logs, and audit logs.
#   Search slow logs, index slow logs, and error logs are useful for troubleshooting performance and stability issues.
#   Audit logs track user activity for compliance purposes.
#   All the logs are disabled by default.
